Beaufort Scale Explained: Understanding the Wind for Sailing

Table of Contents

Last Updated on May 24, 2024 by Boatsetter Team

The Beaufort Wind Scale is a measure of wind speed and accompanying sea state. It is an internationally recognized standardized model created by Irishman Francis Beaufort in 1806, who went on to become a rear admiral in the Royal Navy.

The scale is still used today to estimate wind strengths. Understanding the Beaufort Wind Scale is important for boating and boaters, especially for those looking to go on a sailing adventure .

Reading the Beaufort Scale

The scale has wind speed levels of 0-12 called Forces . Forces are numbered but also have names and include observations and ranges of wind velocity in kilometers, miles, and knots. The speeds are sustained averages, not wind gusts.

Force 0 means the air is still, and the sea state is calm. Forces 1-2 are light air or a light breeze with wind under six knots or 7 mph. Force 3 is a gentle breeze where flags begin to wave, wind velocity tops at 10 knots, and the water develops small waves.

A moderate breeze is Force 4 with 11-16 knots wind speeds. A fresh breeze is Force 5 (17-21 knots), and a Force 6 strong breeze reaches up to 27 knots. At this point, the water forms large waves with lots of foam present.

Force 3-6 are ideal for sailing! Smaller and lighter boats do well around Force 3, while heavier cruisers will hold their own in Force 6. Most sailboats will be reefing or shortening sail starting in Force 5 around 20 knots. Some of this depends on the point of sail; a boat can take more wind when running with it rather than beating into it.

Beyond Force 7 or a near gale, with 28-33 knots wind speeds, things can get dicey with large waves and flying foam. Force 8 is a full gale with winds 34-40 knots. Force 9 is a strong gale with wind up to 47 knots with toppling wave crests and reduced visibility.

Force 10 is a storm with winds up to 55 knots and a rough sea state. A violent storm is a Force 11 with winds up to 63 knots. In this state, ships can become totally obscured as they fall into wave troughs. Force 12 has winds of 64+ knots and is considered a Category 1 Hurricane.

Hurricanes greater than category 1 are not a part of the Beaufort scale.

Pro sailing tip

While most in the US measure wind force in knots, it’s good to be familiar with the Beaufort Scale, especially since international weather forecasters do use it. It’s an especially useful tool when planning your sailboat trip. Also, remember to stay within Force 3-6 for an easy and safe sail.

What Is The Ideal Wind Speed When Sailing?

‍Whether you're using one of the biggest sailboats in the world or a small dinghy boat meant for the water body in your backyard, sailing is all about the wind. It's, therefore, crucial that you understand the wind speed, wind direction, and the ideal wind speed for you.

Even though sailing using the force of the wind is an ancient technique that dates back to the start of human civilization, it's still in use today. For many centuries, sailing was the main mode of long-distance transportation, especially after the invention of sails. Unfortunately, the risks of sailing or otherwise relying on the wind were many. In addition to the fact that reliance on the wind was slow, a substantial number of sailboats and other water vessels were lost. Despite this, speed became so essential, especially when transporting perishable goods such as flowers. But what's the ideal wind speed for sailing? Well, let's find out.

To be honest, there's no single wind speed that can be pinpointed as ideal. This is because what is ideal for you or for the type of sailboat you're using may not be ideal for someone else. That being said, the best wind speed for sailing is one that allows you to sail the boat safely and within your comfort zone, which is generally between 5-12 knots. Keep in mind that sailing at a wind speed that pushes the boat above its normal hull speed is ultimately dangerous.

Again, the ideal wind for sailing may depend on several factors such as your skill level, boat type, your location, your needs and preferences, location, and many other factors. It's all about knowing what you're after and you'll find a good range of wind to work with.

For this reason, we'll not give you a single answer. Instead, we'll look at different ideal winds for sailing and various factors that will help you decide the ideal wind for sailing based on your condition.

But before going into what could be your ideal wind speed for sailing, let's look at some details.

Table of contents

Preparing for Your Sailing Trip

When going out there on the water, the weather should be one of the most important factors to consider. In addition to sudden storms and squalls, chances are you might have to deal with searing heat. In essence, poor weather can seriously spoil your sailing trip. Even worse, poor weather can lead to an emergency situation on the water.

For this reason, it's very crucial that you always check the weather before you set sail. It would be better to postpone your trip if there are chances that you might be caught in the middle of a storm or even a hurricane. You should also stay updated on the weather forecasts and weather patterns to stay ahead in case there's stormy weather.

Measuring Wind Speed

Sailors measure distances in nautical miles. This means that wind speed is measured in nautical miles per hour also widely known as knots. This may be a little longer than a land mile. Let's put it into perspective.

• ‍1 nautical mile = 1 knot = 1.1508 mile on land.
• Therefore, 1 knot = 1.1508 miles per hour

While the speed of the wind is measured in knots, the strength of wind is measured using the Beaufort Wind Scale. This scale was invented in the 18th century by a British naval officer, Admiral Francis Beaufort. This scale ranges from 0-12 in which case 0 is completely calm while 12 is the strongest storm.

Wind Direction and Windward Sailing

Before going into different wind strengths, it's of great importance that you understand what's known as wind direction. This is essentially the direction from which the wind is coming or the point of the compass the wind is blowing. For instance, a north wind blows from the north, NOT to the north.

You've probably been wondering what sailing into the winds is called. Well, this is known as windward sailing and it literally means that your sailboat is moving into the wind. You should, however, keep in mind that a sailboat cannot directly move into the wind. This is because the sails won't create any lift. As a result, the boat will be a little off the wind by about 30 to 50 degrees while sailing windward .

Different Wind Strengths

If you're new to sailing, there are various terms revolving around winds that might get you confused. Let's look at some of them.

Calm winds will range from 0-1 knots. The water becomes so calm that it looks like a mirror. On land, this is the type of wind whereby smoke will rise vertically. Calm winds may not be ideal for sailing given that your sailboat may not even sail.

Light Winds

Light winds can range from 1 to 14 knots and will cause small wavelets in the water while filling up the sails. On land, you may feel the wind on your face, and tree leaves will start moving while wind vanes will show the direction of the wind.

Light winds may affect your wind speed but this will depend on the size of your boat and the type of water you're sailing on. For instance, sailing a small sailboat on a small lake in your hometown may be appropriate for light wind conditions but the very same boat can't handle the same waves and winds in a bigger lake or ocean. Again, the same conditions using a bigger boat may be inappropriate if you're sailing in a coastal area as the conditions will be light.

In essence, light winds are very low and you may get bored while out there on the water.

Moderate Winds

Ranging from 15 to 20 knots, sailing in moderate winds can be really engaging and fun. This is a good working breeze that will make your sails full and the sailboat will be at full speed. On land, the wind will raise dust and small tree branches will start bending.

If you're using a smaller sailboat, it will heel and you may feel uncomfortable for the first few occasions if you aren't used to these conditions. This means that you should sail with experienced sailors who can handle the conditions perfectly well. Alternatively, this may be an ideal condition if you have a larger boat. The boat will sail at maximum hull speed and the conditions will not be a cause of concern for you or the crew.

Strong Winds

With wind speed ranging from 20 to 33 knots, there will be whitecaps everywhere on the water and this might be the right time to shorten your sails. On land, most tree branches are moving and the winding is literally whistling.

If you're sailing on the lake, this isn't the right time to be on the water. This is because the condition is unsafe and there are high chances that you'll ground your sailboat. In an ocean, experienced sailors can handle such a condition. If anything, these are normal conditions if you're planning for offshore sailing.

You should, however, make sure that you use an offshore boat that's designed to help you deal with such conditions. For instance, the boat should have an easy reefing system to enable you to reef the boat with less difficulty.

Ranging from 34 to 47 knots, gale winds will mean that there are foams on the water in well-marked streaks and all boats will head in. On land, small tree branches will break, and walking might be difficult.

Needless to say, these conditions aren't ideal for smaller sailboats or if you're a beginner and still learning how to sail. On the contrary, you can perfectly handle these conditions if you're an experienced sailor with a larger ocean-going sailboat.

Storms or Squall Winds

With the wind speed going above 48 knots, storms are dangerous situations and the seas may have huge waves going over 8 meters. These conditions are not ideal for sailing whatsoever and you should stay at home if possible. But if you're already out there and the tides change, then it would only be wise to implement skills such as heaving to help you ride out of the storm.

So what's the Ideal Wind Speed for Sailing?

As we noted earlier, the best wind speed for sailing may differ from one sailor to the other. Generally speaking, the ideal wind speed should allow you to navigate the boat safely and within your comfort zone. But because we have different comfort zones, let's get more into details and highlight the ideal wind speeds for various situations.

Easiest Wind Speed

When it comes to sailing, the wind is the driving force but it's always wise to know there's a thin line between what's easy and what's difficult or shall we say dangerous wind speeds. Although many beginners may think that sailing in light winds is the ideal situation, this is not always the case. When the wind is so light, it may not fill up the sail. This will not only leave you in drag but sailing will be difficult if there's not enough wind to fill the sail.

That being said, the easiest wind speed for sailing should range from 7 to 10 knots. This is actually ideal if you're still learning how to handle the boat. It's also less risky to capsize at this speed but quite enough to learn the ropes of maneuvering a sailboat.

Ideal Wind Speed for Training

When learning how to sail , the most important things revolve around getting to know the boat and how to handle it. In most cases, you'll want to play it safe and avoid injuring yourself or capsizing the boat. As such, it's always advisable to start at wind speeds of 10 knots or below. This is to enable you to know the boat and how to handle it.

You'll, of course, not become a skilled sailor by staying in the comfort zone or in a situation where you can only handle "7-knots-sunny-beer-and-burgers" kind of weather. The idea here is that you should try different wind speeds not just to overreach your skills a little bit but also to improve and handle varying sailing situations.

As such, you should get out of your comfort zone if you've learned how to handle the boat and train and wind speeds ranging from 15 to 20 knots or in moderate winds. If anything, moderate winds are really fun and engaging.

The most important thing when learning how to sails is to:

• Know the type of wind speed that you're perfect at and can enjoy a ride
• Know the type of wind speed that you're not-so-good at
• Go beyond your comfort zone

By knowing all these, you'll know areas where you need to improve on. All in all, start by training at wind speeds of 10 knots and below until you can handle the boat and then move to around 20 knots to improve your skills.

Minimum Wind Speed

As we noted earlier, trying to sail when the wind is calm or at a speed ranging from 0 to 1 knot is almost impossible. This is because there will be no wind in the sail and the boat will not move. Therefore, the minimum wind speed for sailing is 5 knots. Anything below that will be a waste of your precious time as the boat will not move unless it's a very small sailboat such as the sunfish.

This may be hard to believe, but sailing at minimum wind speed is a skill on its own. Experienced sailors who have mastered this skill will tell you not to over-adjust the sails or over-steer the boat. Instead, just hang back the sails, relax, and the sails will catch enough wind to get you into motion.

Other Factors

We, of course, noted earlier that there are other factors that may determine the ideal wind speed for sailing. Let's look at them.

The type of boat you're using may determine whether or not the wind speed is ideal for you.

• Sunfish boats - Make sure that you stay at wind speeds below 15 knots. Anything above that may overpower the boat and may leave you in a precarious if not deadly situation.
• Up to 26 feet boats - These types of boats sail best in wind speeds ranging from 10 to 20 knots.
• Over 26 feet boats - These are heavy boats that can perfectly handle wind speeds ranging from 15 and 25 knots.

Should you avoid Windy Conditions?

To be very honest, windy conditions can be deadly and you should always avoid them. Remember, your safety should always come first. But what happens if you go out there thinking that the conditions are ideal only to find yourself in foul weather or stormy situations? Believe it or not, you'll at, one point, run into the worst moment and you'll have to figure out how to deal with the situation and how to stay safe.

For this reason, you should always be prepared for such situations. The first thing is to always dress for the action, have your lifejacket, and get in a situation where you can learn how to reef down. While you can smoothly sail in flat waters, look for wind speeds that are just above 20 knots. Make sure that the boat is designed for such conditions and have an appropriate reefing system.

When it comes to reefing, the golden rule is that you should have reefed already if you're thinking about reefing. The best way to decide when to reef is by judging the degree of heel and weather helm produced by the boat when sailing in high winds. When to reef may also depend on the size and stability of your boat. You should, therefore, reef if your boat is heeling extremely or if you expect high winds.

Bottom Line

To this end, the ideal wind for sailing may vary from one person to another. What's ideal for you may not be ideal for another person. Again, the ideal wind speed for sailing may depend on your skill level and the type of boat you're using. If you're beginning, you can choose somewhere between 7 to 10 knots until you're comfortable enough to handle the boat. You can then move on to moderate winds of 15 to 20 knots if you want fun, engaging, and challenging situations.

All in all, it's important to stay safe while out there on the water by avoiding very windy or stormy conditions.

Understanding Wind Speed and Its Impact on Boating

You need to under­stand wind speed and how it affects boat­ing. When you’re out on the water, the wind can be your great­est ally or your worst ene­my. It has the pow­er to pro­pel your boat for­ward, allow­ing you to sail freely and effort­less­ly. How­ev­er, if the wind is too strong, it can cre­ate dan­ger­ous con­di­tions that can put your free­dom at risk.

Wind speed is mea­sured in knots, with one knot equal­ing one nau­ti­cal mile per hour. The high­er the knot val­ue, the stronger the wind. As a boater, it’s impor­tant to be aware of the wind speed before set­ting sail . This infor­ma­tion can be obtained from weath­er reports or by using an anemome­ter, a device that mea­sures wind speed.

Under­stand­ing wind speed is cru­cial because it direct­ly impacts your boat’s per­for­mance. A light breeze of around 5–10 knots is ide­al for a leisure­ly sail. It pro­vides a pleas­ant expe­ri­ence, allow­ing you to enjoy the free­dom of being on the open water. How­ev­er, as the wind speed increas­es, so does the chal­lenge. Strong winds of 20 knots or more can make maneu­ver­ing your boat dif­fi­cult and poten­tial­ly dan­ger­ous.

Is 20mph wind bad for boat­ing

It depends on the size of the boat and the expe­ri­ence of the crew . Gen­er­al­ly speak­ing , winds of 20mph can make for chal­leng­ing sail­ing con­di­tions and can cause chop­py waters . It would be wise for inex­pe­ri­enced bo aters to stay ashore if the wind reach­es 20 mph , as these con­di­tions can be dif­fi­cult to han­dle . Exper ienced boat crews should use extra cau­tion and should be aware of the poten­tial for waves and wind gust s . For more info check how does a sail­boat sail into the wind .

Wind Speed and Boating

The first thing to con­sid­er when it comes to wind and boat­ing is wind speed. The wind speed should be tak­en into account when decid­ing whether or not it is safe to go out on the water. Wind speeds that are too high can cause dan­ger­ous con­di­tions, such as high waves, strong cur­rents, and reduced vis­i­bil­i­ty. Here’s what you need to know about wind speed and boat­ing:

Wind Speed and Boat Size

The size of your boat should be tak­en into con­sid­er­a­tion when deter­min­ing what wind speed is safe for boat­ing. Small­er boats can be eas­i­ly tossed around by the wind and waves, so it is impor­tant to be aware of wind speed and adjust accord­ing­ly. Gen­er­al­ly, winds of 10–15 knots (11–17 mph) can be safe for small boats, while larg­er boats can han­dle stronger winds.

Wind Speed and Sea Conditions

The sea con­di­tions should also be tak­en into con­sid­er­a­tion when deter­min­ing what wind speed is safe for boat­ing. If the sea is chop­py, it can be more dif­fi­cult to maneu­ver a boat and the waves can cre­ate a more dan­ger­ous sit­u­a­tion. In these cas­es, the wind speed should be much low­er than if the sea was calm. Winds of 5–10 knots (5.7–11.5 mph) can be con­sid­ered safe for chop­py sea con­di­tions.

Wind Speed and Personal Experience

When it comes to boat­ing, each person’s expe­ri­ence and com­fort lev­el will be dif­fer­ent. If you are an expe­ri­enced boater, you may be able to han­dle high­er wind speeds than some­one who is just start­ing out. If you are not sure about your expe­ri­ence lev­el, it is best to err on the side of cau­tion and stick with low­er wind speeds.

Weather Forecasting

When it comes to boat­ing, weath­er fore­cast­ing is an impor­tant tool. By check­ing the weath­er fore­cast before head­ing out on the water , you can get an idea of what the wind speed is going to be. This can help you make an informed deci­sion about whether or not it is safe to go out on the water.

Wind Direction

In addi­tion to wind speed, the wind direc­tion should also be tak­en into con­sid­er­a­tion when boat­ing. Winds that are blow­ing in the same direc­tion as the cur­rent can cre­ate strong waves and make it dif­fi­cult to steer a boat. It is impor­tant to be aware of wind direc­tion and make sure that you are not head­ing into an area with strong winds.

Emergency Plan

It is also impor­tant to have an emer­gency plan in place before head­ing out on the water. This should include a plan for what to do if the boat cap­sizes or if some­one falls over­board. It is impor­tant to make sure that every­one on board is famil­iar with the plan and knows what to do in case of an emer­gency.

It is impor­tant to make sure that you have the right safe­ty equip­ment on board your boat. This should include life jack­ets for every­one, a first aid kit, and a dis­tress sig­nal. It is also impor­tant to make sure that every­one on board is famil­iar with the safe­ty pro­ce­dures for the boat.

Make sure that the boat is in good con­di­tion before head­ing out on the water. This means check­ing the hull and engine for any signs of dam­age or wear. If any main­te­nance is need­ed, it should be done before head­ing out. Prop­er main­te­nance can help to pre­vent acci­dents and ensure that the boat is in good work­ing order.

The Effects of Wind on Boat Handling and Control

When wind speeds reach 15 knots or high­er, it can sig­nif­i­cant­ly impact your abil­i­ty to han­dle and con­trol your boat. The effects of wind on boat han­dling and con­trol can be chal­leng­ing, but with the right knowl­edge and skills, you can nav­i­gate through it smooth­ly. Here are a few things to keep in mind:

• Increased resis­tance : As the wind picks up, it cre­ates more resis­tance against your boat, mak­ing it hard­er to maneu­ver. You may need to adjust your course and speed to coun­ter­act the force of the wind.
• Sail trim­ming : Prop­er­ly trim­ming your sails becomes cru­cial in windy con­di­tions. Adjust­ing the sail angle and ten­sion can help you main­tain con­trol and pre­vent the boat from heel­ing exces­sive­ly.
• Gusts and lulls : Wind gusts can come sud­den­ly and with great force, caus­ing your boat to heel or veer off course. Antic­i­pat­ing these gusts and adjust­ing your sails and course accord­ing­ly is essen­tial. On the oth­er hand, lulls in the wind can also affect your con­trol, requir­ing you to make adjust­ments to main­tain momen­tum.

Assessing Wind Conditions for Safe Boating

Assess­ing wind con­di­tions and deter­min­ing the appro­pri­ate lev­el of wind for safe boat­ing can be cru­cial for a suc­cess­ful and enjoy­able out­ing on the water. As some­one who desires free­dom, you want to make sure you have the free­dom to nav­i­gate the waters with­out any unnec­es­sary risks.

To assess the wind con­di­tions, start by observ­ing the speed and direc­tion of the wind. Use a hand­held anemome­ter or sim­ply feel the wind on your face. Keep in mind that wind speed can vary at dif­fer­ent heights, so it’s impor­tant to assess the wind at the lev­el where you’ll be oper­at­ing your boat.

In addi­tion to wind speed, also con­sid­er the poten­tial gusts. Gusts can be sud­den and strong, mak­ing it dif­fi­cult to con­trol your boat. If you notice fre­quent gusts, it may be a sign that the wind con­di­tions are too strong for safe boat­ing.

Final­ly, take into account your own boat­ing expe­ri­ence and skill lev­el. Even if the wind con­di­tions seem man­age­able, if you’re a begin­ner or not con­fi­dent in your abil­i­ties, it may be best to wait for calmer con­di­tions.

Essential Safety Precautions in Windy Boating Conditions

To ensure your safe­ty, it’s impor­tant to fol­low essen­tial pre­cau­tions when boat­ing in windy con­di­tions. The thrill of the wind in your hair as you nav­i­gate the open waters is an exhil­a­rat­ing expe­ri­ence, but it’s cru­cial to pri­or­i­tize safe­ty at all times. Here are some essen­tial safe­ty mea­sures to keep in mind:

• Check the weath­er fore­cast : Before set­ting sail, always check the weath­er fore­cast. Windy con­di­tions can quick­ly esca­late, and it’s impor­tant to be aware of any poten­tial storms or gusts that could pose a risk to your boat­ing adven­ture.
• Secure all loose items : Strong winds can cause items to fly around on the boat, pos­ing a dan­ger to both you and your fel­low pas­sen­gers. Make sure to secure loose items such as cool­ers, fish­ing gear, and per­son­al belong­ings before set­ting off.
• Wear appro­pri­ate safe­ty gear : In windy con­di­tions, it’s cru­cial to wear appro­pri­ate safe­ty gear such as life jack­ets, hats, and sun­glass­es. These items won’t only pro­tect you from poten­tial acci­dents but also shield you from the sun and wind.

By fol­low­ing these essen­tial safe­ty pre­cau­tions, you can enjoy the free­dom and excite­ment of boat­ing in windy con­di­tions while ensur­ing your safe­ty and the safe­ty of those around you.

Tips for Maneuvering and Navigating in Windy Conditions

To effec­tive­ly nav­i­gate in windy con­di­tions, keep your steer­ing steady and your eyes focused on the direc­tion ahead. Main­tain­ing a steady course is cru­cial in windy con­di­tions as it allows you to main­tain con­trol of your boat. Trust your instincts and feel the wind’s direc­tion and inten­si­ty. Adjust your sails or motor accord­ing­ly to main­tain sta­bil­i­ty and con­trol. It’s impor­tant to antic­i­pate gusts and adjust your speed accord­ing­ly. Slow­ing down can help you main­tain sta­bil­i­ty and pre­vent your boat from being pushed off course.

When nav­i­gat­ing in strong winds, it’s essen­tial to pay atten­tion to your sur­round­ings. Keep an eye out for oth­er boats, obsta­cles, and changes in water con­di­tions. Stay alert and be pre­pared to make quick deci­sions to avoid poten­tial haz­ards. Look for shel­tered areas or nat­ur­al bar­ri­ers that can pro­vide some relief from the wind. Uti­lize these areas to your advan­tage and nav­i­gate through them when­ev­er pos­si­ble.

Com­mu­ni­cate with your crew and estab­lish clear com­mu­ni­ca­tion sig­nals. This will help you coor­di­nate maneu­vers and respond quick­ly to chang­ing con­di­tions. Keep your crew informed about the wind direc­tion and any poten­tial haz­ards.

When to Decide It’s Too Windy for Boating

Decid­ing if it’s too windy for boat­ing can be chal­leng­ing, but you need to con­sid­er the safe­ty of your­self and your pas­sen­gers. While it’s tempt­ing to head out on the water and feel the free­dom of the wind in your hair, it’s impor­tant to make wise choic­es to avoid any poten­tial dan­gers. So, how do you know when it’s time to call off your boat­ing adven­ture? Take a look at the table below to help you assess the wind con­di­tions and make an informed deci­sion.

How do I determine if the wind is too strong for boating?

The wind speed is a key fac­tor in deter­min­ing whether it’s safe to go boat­ing. As a gen­er­al guide­line, winds exceed­ing 20 knots (23 mph) are con­sid­ered strong and can make boat­ing chal­leng­ing and poten­tial­ly unsafe. It’s impor­tant to mon­i­tor weath­er fore­casts and use your judg­ment based on your boat’s size, your expe­ri­ence lev­el, and the spe­cif­ic con­di­tions of the water­body you’re plan­ning to nav­i­gate.

Can I go boating in moderate wind conditions?

Boat­ing in mod­er­ate wind con­di­tions is gen­er­al­ly safe, but it’s essen­tial to con­sid­er your com­fort lev­el, the size and type of your boat, and your expe­ri­ence as a boater. Mod­er­ate winds can cre­ate some chop­py waters and may require addi­tion­al cau­tion, espe­cial­ly for small­er boats. Always assess the wind speed and direc­tion before head­ing out and be pre­pared to adjust your plans if the con­di­tions wors­en.

Are there any specific wind speed limits for boating?

While there are no uni­ver­sal­ly defined wind speed lim­its for boat­ing, it’s impor­tant to be aware of any local reg­u­la­tions or guide­lines in your area. Some regions may have spe­cif­ic restric­tions or rec­om­men­da­tions based on wind speeds or weath­er con­di­tions.

When it comes to boat­ing, it is impor­tant to be aware of the wind speed and con­di­tions. Winds that are too strong can cause dan­ger­ous con­di­tions on the water, from strong waves to reduced vis­i­bil­i­ty. It is impor­tant to be aware of wind speed and direc­tion, and make sure that you have the right safe­ty equip­ment on board. By fol­low­ing these guide­lines, you can make sure that you stay safe while out on the water.

How to Read the Wind

• By Gary Jobson
• October 22, 2024

We can’t see the wind, but we can see what it is doing to many objects on the water. Understanding the patterns and trends of the ever-­changing wind helps us sail faster, more efficiently, and on a more direct course toward our destination.   

Reading the wind is one of the great joys of sailing. Start by wearing sunglasses to dampen glare. This makes it easier to detect small changes of the ripples that wind causes on the water. I use prescription sunglasses to help me read the wind.  

Stand up in the boat so that you can see farther. Study one section of the horizon at a time. In a minute or two, you will be able to recognize what the wind is doing. 

Start by looking at the wind within 10 boatlengths, and then extend your view farther out, eventually all the way to the horizon. Study the patterns. Out loud, say where you think the wind is best.  

There are many clues. The first indicator is the water. Dark patches with ripples close together indicate more wind. Look for the intensity of the patches. That means puffs. You can also see if the puffs are coming from different directions.   

The next indicator is your sails. The wind flows around the sails and lets you know exactly what is happening around your boat. I use an apparent-wind indicator (a masthead fly) to see what direction the wind is flowing. Other boats sailing in your vicinity are a helpful source of information too. If, for example, you see a boat well ahead of you steering a higher course, that suggests you are about to be lifted (able to sail a higher course toward your destination).  

A change of direction that forces you farther off course is called a header. Often, when wind changes direction, it is part of a puff with more ­velocity. Anticipate a puff just before it flows into your sails. If it is a strong gust, be prepared to ease out your sails and head up a few degrees to lessen the effects of the puffs.  

Flags flying on the shoreline are helpful in trying to figure out if the wind is going to change direction. A set of anchored boats is another helpful source. (Be mindful that current flow can affect how a boat sits at anchor.) 

If a strong gust approaches your boat, then alert the rest of the crew that you are about to get a blast of wind. Crews don’t like surprises. Suddenly heeling over can startle an unsuspecting crew. 

Smokestacks are another good source of wind-direction information. A smokestack is high in the air and indicates what direction the wind is blowing at a higher elevation.

While you are sailing, keep a mental note of how each puff of wind is affecting your boat. The patterns repeat throughout the day. On a light-air day, head for a set of clouds. Often, good wind is underneath clouds. On a ­very-light-wind day, you can feel a subtle breeze on your neck. Wet a ­finger and hold it in the air, and you can feel which ­direction the wind is blowing.

Buddy Melges once told me that he looks to see what direction cattle are standing onshore so they can feel the wind on their backsides.

Thermal factors have a big impact on wind. When air heats up on land, it rises. A cooler breeze over the water fills in to take the place of the rising air. This is called a thermal or a sea breeze. 

Before sailing, take a few minutes to check out different forecasts by weather services. My favorites include Windy, PredictWind, SailFlow and the National Weather Service. I like looking at more than one source to get a sense of what might happen while I am on the water. 

For long-distance passages, consider subscribing to a private weather service. On an expedition to Antarctica, our crew engaged a weather service that gave us accurate forecasts every 12 hours. We received the information via email on a satellite phone. Many ­grand-prix racing crews use customized weather services as well.

The locals can be helpful. A gardener at a yacht club used to give me tips every Saturday before I went out racing. He would say: “There is a lot of dew on the grass this morning.  There’s going to be a strong breeze from the south.” Or: “I noticed cobwebs on the fence. Probably going to be a westerly wind today.” I smiled at the lore of the gardener, and yet his forecast generally proved accurate, so I always factored his commentary into my thinking.

Expect the wind to be choppy and confused in harbors and around moored boats. You are better off sailing in open water. Areas with many powerboats chop up the waves and cause confusion reading the wind. I try to sail in areas with as few power vessels as possible.  

Superstar sailor Buddy Melges once told me that he looks to see what direction cattle are standing on the shoreline so they can feel the wind on their backsides. Melges also advised watching the direction birds take off because they usually fly into the wind to generate lift.

When you sail into a gust of wind, it helps to use your sail trim, steering, and weight placement to maintain an even keel. When a boat heels over too far, it makes leeway. The rudder and keel stall, making it difficult to steer, and the boat slows down.  

When I am daysailing, I like to keep my boat sailing fast. The helm feels better, and the boat performs better. So, I ask the crew to sit to windward in a breeze and to leeward in light wind. If you plan to make a maneuver, let the crew know well in advance so that they will be prepared to switch sides of the boat. Reading the wind accurately will help you understand when it is time to tack or jibe.

More than anything, practice. I’ve spent my entire career studying the wind. Predicting what is going to happen will make your sailing more enjoyable.

What is the Ideal Wind Speed for Sailing? A Comprehensive Guide

Sailing is a popular recreational activity enjoyed by many people around the world. It’s all about the wind, and understanding wind speed is crucial for a successful and enjoyable sailing experience. But what is the ideal wind speed for sailing? This comprehensive guide will provide all the information needed to answer this question.

Table of Contents

Understanding Wind Speed

When it comes to sailing, wind speed is one of the most important factors to consider. Understanding how wind speed affects sailing is crucial to ensure a safe and enjoyable experience on the water.

Wind speed is measured in knots, with one knot equaling 1.15 miles per hour. The ideal wind speed for sailing depends on several factors, including the size of the boat, the experience level of the sailor, and the intended use of the boat.

In general, most sailors agree that around 10 knots of wind are the best wind speed for sailing. This wind speed provides enough power to move the boat efficiently, but not so much that it becomes difficult to control. For beginners, it is recommended to start with winds of under 10 knots to get a feel for the handling of the boat.

It is important to note that wind speed can vary greatly depending on the location and weather conditions. A wind speed of 10 knots may be ideal in one location, but in another location, it may be too much or too little. It is essential to check weather forecasts and wind reports before setting sail to ensure safe conditions.

Additionally, it is important to understand the difference between true wind and apparent wind. True wind is the actual wind speed and direction, while apparent wind is the wind that the boat experiences due to its movement through the air. Apparent wind can be affected by the boat’s speed and direction, and it is important to take this into account when sailing.

Ideal Wind Speed for Sailing

Sailing is a sport that requires a lot of factors to be just right, and wind speed is one of the most important. The ideal wind speed for sailing depends on a variety of factors, including the type of boat, the experience level of the sailor, and the conditions of the water. Here are some general guidelines for the ideal wind speed for sailing:

• For absolute beginners, wind speeds under 10 knots are ideal. Anything under 10 knots will prevent capsizing and allow beginners to get a feel for the boat.
• For more serious training, wind speeds between 15-20 knots are ideal. This range allows for more advanced techniques and maneuvers to be practiced.
• For heavy offshore boats, wind speeds between 20-25 knots are ideal. Anything under 12 knots and the boat may not even come to life, while 25 knots and up is considered rough for any small/mid-sized boat.
• Most sailors agree that around 10 knots of wind are the best wind speed for sailing, as an average. This range allows for a good balance of speed and control.

It’s important to note that these are general guidelines and the ideal wind speed for sailing can vary depending on a variety of factors. Experienced sailors may prefer higher wind speeds, while beginners may prefer lower wind speeds. It’s always important to assess the conditions and adjust accordingly.

Factors Affecting Ideal Sailing Wind Speed

When it comes to sailing, wind speed is a crucial factor that determines how fast a boat can go and how well it can maneuver. However, the ideal wind speed for sailing is not a fixed number and can vary depending on several factors. In this section, we will explore some of the key factors that affect the ideal sailing wind speed.

Boat Size and Type

The size and type of boat can have a significant impact on the ideal sailing wind speed. Smaller boats such as dinghies and catamarans can sail in lighter winds, typically between 5 to 15 knots. On the other hand, larger boats such as keelboats and yachts require stronger winds to sail effectively, usually between 15 to 25 knots. It’s important to note that these are general guidelines, and the ideal wind speed can vary depending on the boat’s specific design and features.

Sailor’s Skill Level

Another critical factor that affects the ideal sailing wind speed is the sailor’s skill level. Beginners and novice sailors are advised to sail in lighter winds, typically under 10 knots, to avoid capsizing. As sailors gain more experience and confidence, they can gradually increase the wind speed to 15 to 20 knots. Advanced sailors and racing enthusiasts can sail in stronger winds, up to 25 knots, but require a high level of skill and experience to handle the boat safely.

Weather and Sea Conditions

The weather and sea conditions can also affect the ideal sailing wind speed. In general, calm seas and clear skies are ideal for sailing, but they usually come with lighter winds. On the other hand, rough seas and stormy weather can create stronger winds, but also pose higher risks and challenges for sailors. Other factors such as wind direction, waves, and currents can also affect the ideal sailing wind speed and require careful consideration and adjustment.

Safety Measures for Sailing in Different Wind Speeds

When sailing, it is crucial to take safety measures to ensure the safety of the crew and the boat. Wind speed plays a significant role in determining the safety measures to be taken. Here are some precautions to take when sailing in different wind speeds.

Light Wind Precautions

Light winds of 5-12 knots are ideal for sailing, but it’s essential to take precautions to avoid accidents. Here are some light wind precautions to take:

• Keep a lookout for other boats and obstacles in the water.
• Keep the sails trimmed and make sure they are not luffing.
• Use a harness and a safety line when on deck.
• Keep the crew weight centered and avoid sudden movements that can cause the boat to capsize.

Moderate Wind Precautions

Moderate winds of 15-20 knots require more caution when sailing. Here are some moderate wind precautions to take:

• Reef the sails to reduce the sail area and prevent the boat from heeling too much.
• Keep the boat speed under control and avoid surfing down waves.
• Wear life jackets and harnesses at all times when on deck.

Strong Wind Precautions

Strong winds of 20-25 knots or more require extreme caution when sailing. Here are some strong wind precautions to take:

• Use a storm jib or a trysail if the wind is too strong.
• Consider heaving to or running before the wind if the conditions become too severe.

How to Measure Wind Speed

Measuring wind speed is crucial for sailing, as it allows sailors to determine the ideal wind speed for their boat, as well as to make informed decisions about their course and sail adjustments. There are several methods for measuring wind speed, including:

Beaufort Wind Scale

The Beaufort Wind Scale is a system that measures wind speed based on observable effects on the water and surrounding environment. It ranges from 0 (calm) to 12 (hurricane-force winds). While it is subjective and varies depending on the observer’s experience, it can provide a general idea of wind speed.

Anemometers

Anemometers are instruments that measure wind speed and direction. They come in various forms, including handheld devices and fixed instruments on boats. Some anemometers are mechanical, while others are electronic. Electronic anemometers are more accurate and provide real-time data.

Knots are a unit of measurement used primarily by sailors to measure speed in nautical miles per hour. One knot is equal to one nautical mile per hour. To measure wind speed in knots, sailors can use a handheld anemometer or estimate based on the Beaufort Wind Scale.

Weather Apps

Many weather apps provide real-time wind speed data for specific locations. While they may not be as accurate as anemometers, they can provide a general idea of wind speed and direction.

Techniques for Sailing in Various Wind Speeds

Light wind sailing techniques.

When sailing in light winds, it is important to maximize the efficiency of the sails and minimize drag. This can be achieved by using the following techniques:

• Keep the sails full and use telltales to ensure they are trimmed correctly.
• Use light, flat sails that are designed for light winds.
• Keep the boat moving by constantly adjusting the sails and steering.
• Keep weight to the center of the boat to reduce drag.

Moderate Wind Sailing Techniques

Moderate winds are ideal for sailing, and with the right techniques, you can sail faster and more efficiently. Here are some techniques to consider:

• Use a sail plan that is appropriate for the wind speed.
• Use a sail shape that is optimized for the wind conditions.
• Use the telltales to ensure the sails are trimmed correctly.
• Move weight to the leeward side of the boat to reduce heeling.

Strong Wind Sailing Techniques

Sailing in strong winds can be challenging, but with the right techniques, it can also be exhilarating. Here are some techniques to consider:

• Reduce sail area to prevent the boat from becoming overpowered.
• Use a sail shape that is optimized for high wind conditions.
• Keep the boat flat by moving weight to the windward side.
• Use the boom vang to control the shape of the mainsail.
• Use the traveler to adjust the angle of the mainsail.
• Use the jib sheet to control the shape of the jib.

In conclusion, there is no one ideal wind speed for sailing that applies to all boats and all sailors. The ideal wind speed for sailing depends on various factors, including the type of boat, the sailor’s experience level, and the weather conditions.

The Perfect Wind Speed for Sailing – How Much Wind Do You Really Need? ANSWERED

If you’re new to sailing, you might be wondering what the best sailing wind speed is. It seems like an easy question, but the question strikes at the heart of the things that go into sailing a boat and being a good skipper. 

Of course, there is no one perfect wind speed for sailing. Every skipper on the ocean will have a different answer. One will like the smooth and steady ride they get from their coastal cruiser when the wind blows at 12 knots. Another, sailing heavy offshore boats, won’t even bother putting the sails up with a minimum wind speed of 12 knots or less—but they don’t start having fun until it’s 18-20 knots. 

But there’s even more! Those same two skippers might be handed those conditions one day and still complain! Now, 12 knots of wind on the nose means hours of tacking or running the motor for the coastal cruiser. The offshore sailor isn’t making enough progress downwind in 18 knots because the seas have built up too high from a storm and the ride is rough. On this day, neither skipper is happy with their usual comfortable sailing setup!

What is the ideal wind speed for sailing, wind speed in knots vs mph, the beaufort wind scale, true vs apparent wind on sailboats, good sailing wind speed for sailing upwind vs downwind, boat displacement and agility, sailing in various weather conditions and wind speeds, sail selection, the importance of reefing, wind speed and risk management, faqs — best wind speed for sailing.

To answer this question, we must make a few assumptions.

• You’re new to sailing and gaining experience 
• You’re on a moderate-sized cruising boat, not a dinghy or a racer
• You’re looking to make miles and travel, not enjoy a lazy day on the water
• You are more interested in the comfort of your crew than getting there as fast as possible

In other words, this article assumes that you’re the average cruising sailor, traveling for pleasure to see the world by boat. So, if you are a weekend warrior out for the annual small boat race on the river, you might have completely different answers!

If these assumptions apply to you, you’ll probably find that the best sailing days are when the wind blows between 10 and 15 knots. This is enough wind to move even the heaviest boats, although not always very fast. It’s also a safe speed that any cruising-sized boat can handle easily, with the sails still being easy to handle and the boat easy to steer.

As you gain experience you will expand your comfort zone, as long as you boat safely and continue having fun. Once the winds start getting above 25 knots, even many experienced sailors will stay in port. High winds mean more serious training and large waves. When you’re in it for the fun, you’ll likely opt for the most comfortable sailing days, not the most challenging.

How are Wind Speeds Measured?

Before discussing the best wind speed for sailing, we should agree on how to measure the wind speed and look at how sailors get these numbers and interpret them.

One important consideration is how you get your information. For example, many boaters use apps and websites to calculate wind speed from global weather models like the GFS or the ECMWF. The problem with these numbers is that they are forecasts made on many assumptions and estimations that may not be perfect. They are especially limited in places where land interactions can drastically change the local wind patterns.

Besides weather forecasts, boats can get their wind measurements from buoy observations or their own boat’s anemometers (wind vanes). But anemometers have limitations too, and they are often not calibrated very well. Their location makes a big difference, too, since most weather forecasts and official observations are made for 10 meters off the water. So a deck-level wind vane will read a different number than a masthead-mounted unit.

Finally, there’s also the difference between stead winds and gusts. There seem to be many sailors who look at the steady wind forecast and ignore the gusts and then complain about how much windier it was than the forecast stated! 

Remember when thinking about wind speeds for sailing to compare apples to apples. Nearly everything you measure on a boat is in knots—your speed over ground, hull speed, and the wind speeds you should put in a reef. So if your weather app is feeding you the information in miles per hour (MPH), do yourself a favor and eliminate the confusion. See if you can find an app that makes the conversion for you, or remember that 1 knot is equal to 1.15 statute miles per hour.

The Beaufort scale is an old system for measuring wind speed based on the conditions that a sailor can observe out on the water. After all, our focus on the precise wind speed as displayed on a digital indicator is a modern fixation. Sailors have been plying the seas for generations without that technology, although having access to the information has undoubtedly made traveling by sea much safer.

Still, the wind scale helps understand the realms of wind speed and the associated conditions in each. It is not just the wind that should concern a sailor. They must also consider the sea state–the height of wind-blown waves plus the ocean swell. 

The Beaufort scale is measured from 0 (dead calm) to 12 (survival storm conditions or hurricane). Distinct changes in the sea state mark each force. Knowing the Beaufort forces enables a sailor to estimate the wind force in knots without an instrument. 

There’s a big difference between the wind on the water and the wind on the boat. This concept is the definition of “apparent wind.” Apparent wind is that which is felt on the deck of the boat. It changes dramatically depending on the boat’s speed and direction. The opposite of apparent wind is “true wind,” which is the wind speed and direction on the water, without the effects of the boat.

It’s best explained through an example. Let’s imagine a hypothetical sailboat that can sail in any direction—even directly into the wind. Maybe it’s not sailing–it’s just motoring! 

The wind is blowing out of the north at 10 knots. Our sailboat makes 5 knots—no matter which direction it is going.

If the boat is pointed north and directly into the wind, the apparent wind felt on the boat’s deck is 15 knots—10 knots of wind PLUS 5 knots of motor/sailing power. This is the wind in its sails, the breeze on your face, and everything else. Since 15 knots is a better speed to sail a boat, an upwind sail probably feels pretty good and might be called a “good working breeze.” 

What if the boat turned around and went south? Then the apparent wind on deck would be only 5 knots—10 knots of wind MINUS 5 knots of sailing speed. It’s worth noting that most cruising boats do not sail well in winds less than 10 knots and probably will not be making way in winds of 5 or less.

And finally, what if the boat were on a beam reach, headed either due east or west? The apparent wind would be 10 knots since there is no component of the vessel’s speed to add or subtract. 

For all points in between, the apparent wind would be something between 15 (maximum) and 5 (minimum). The exact amount would depend on how close to the wind direction the boat is maneuvering. 

How Much Wind Do You Need to Sail?

The glimpse into the apparent wind in the example above probably provides clues as to how complicated the question of wind speed is on a boat. Now, let’s look at some of the other factors that play into this calculus.

The example above demonstrates that the best wind speeds for sailing depend significantly on the direction you’re going. There’s an adage—A sailor cannot change the wind, but they can adjust their sails. It’s just one more example of why traveling on a sailboat is challenging.

Generally, if you need to sail to a downwind destination, more true wind is favorable. This is because your apparent wind will be lower, so it takes more true wind to move the boat. Additionally, downwind sails are generally more comfortable anyway, since you are sailing with following seas and not pounding into it. 

In our example above, a cruising boat trying to make miles probably could not be headed south without running its motor. If they were headed due north, they’d either have to tack back and forth , motor into the wind, or perhaps motor sail. 

The opposite is true about sailing into the wind. If you’re on a beat, the best wind speed for your sail may be just enough to get the boat near its hull speed. Anything more may produce seas that slow the boat down.

Some of these effects have everything to do with the boat you’re standing on. Every sailboat in the world was designed for a specific set of circumstances. Some are designed very light with lots of sail area, while others are heavier to provide softer rides in rough seas and carry a lot of weight. Know your boat and know what it can and can’t do. Don’t expect a heavily laden, full keel ocean cruiser to sail downwind in 5 knots of apparent wind. 

The choices might be different on a race boat that sails well in light air. The boat might have a large spinnaker, be lightly built and lightly loaded, and be able to sail well downwind in 5 knots of apparent wind. Sailing upwind, it might have better tacking angles and make better VMG (velocity made good, the speed at which you head directly towards your destination). Of course, this boat can travel faster, but it likely can’t hold all your stuff and allow you to live comfortably.

You can draw the same similarities in the catamaran and multihull sailing world. Just because it’s a catamaran does not mean that it will always sail fast. Many cruising catamarans are heavy, especially those that have been kitted out for living aboard. It might win a race with the monohull above sailing downwind in 5 knots of wind. Where the monohull is ghosting along at 2 knots, the cruising catamaran might be doing 2.5 or 3 knots. 

A look at the Beaufort wind scale provides another glimpse into factors that affect sailors. In anything more than a fresh breeze, the sea state begins playing a prominent part of the wind speed equation. The sea is constantly changing, and driving a sailboat up and down mountainous seas is like driving a car over hilly roads. The boat will slow down going uphill and surf down the wave quickly as it slides downhill. 

But a lot of that depends on the timing of the seas. During big storms, seas build up for hundreds of miles in the open ocean and have a big period between them. So big ocean swells might not have much effect on a boat’s progress.

But many times in near-shore waters and places with currents, wind-driven waves pile up. When the wave period (measured in seconds) is equal or less to the wave height, they are called square waves. Square waves produce a very uncomfortable chop that can slow the progress of even the stoutest sailboat.

Regardless of the wave’s shape, the quality of the ride is important inside the vessel. A rough ride can be invigorating and fun if out sailing for an afternoon. But, if sailing overnight, rough seas taken too fast can become uncomfortable. On extended passage, you must take crew fatigue into account. 

The takeaway is this—when figuring out the best wind speed for sailing, the choice can’t be made while ignoring the sea state. The perfect wind speed for sailing on a calm, protected bay might be way too much for open water, or you might need to begin reefing sooner. 

Finally, all boats are limited by the sails they have onboard. Most cruising sailors make do with a standard mainsail and a furling jib or genoa. Without adding a foresail designed explicitly for light airs, like an asymmetrical spinnaker, gennaker, or code zero, the boat will likely need 15-20 knots of true wind to sail at hull speed downwind. 

On the other end of the spectrum, some boats might be risky to take out in conditions beyond a strong breeze without adding robust storm sails. Furling sails can and do come unfurled unexpectedly, and most furling systems are not built to withstand gale or storm-force conditions without careful use and constant inspections for chafe. 

All of this highlights another vital topic in sailing— how to reef a sail . The ability to shorten sails to operate safely in higher winds is an integral part of negotiating the variety of conditions you will encounter on the water. 

If you’re a day sailor, it’s possible you could pick your conditions and never have to reef. But reefing is essentially good boat handling—it is the ability to drive the car without having the “pedal to the metal” all the time. Controlling the power your sails make will make the boat sail better. It will reduce weather helm, excessive heeling, and in some cases, can increase your speed by increasing efficiency.

In summary, what is the ideal wind speed for sailing? The answer is—it depends! It depends on your boat, your skill and experience, on the conditions on the water, on the direction you’re going, and probably many other things not listed here. 

The fundamental takeaway should be this—as you grow as a sailor, you must learn to handle your boat in various realistic conditions. But at some point, the risk of danger outweighs the benefits. At 10 knots, the risks are low. At 20 knots, most cruising boats can handle almost anything, but reefing is a good idea. At 30 knots, if you aren’t reefed and in control, things can go bad quickly. Finally, at 40 knots of wind or more, you should be heavily reefed for heavy weather. 

One parting thought–remember that boating isn’t always about sailing. Most of us have to return to a crowded marina and a tight slip after a sporty day of sailing, and most sailboats are not great when being handled in close quarters. So until you’ve had some safe high wind close-quarters maneuvering in your boat, make sure conditions will allow you to dock safely.

What is the best wind speed for sailing?

The best wind for sailing is the one that propels the boat without using the motor in the direction you want to go, which provides a comfortable and safe ride. 

Unfortunately, no sailor can control the speed of the wind for sailing. So instead, sailors learn to control what they can. They can put out or take in sail, they can set a different course, they can start their motors, or they can stay in port and go sailing another day. 

How windy is too windy for sailing?

It depends on your boat and your experience level. With its sails reefed, you can safely sail most cruising sailboats in winds up to 30 knots. Beyond the 30 knot line, most pleasure sailors will choose to stay in port to avoid the rough ride and extra work it will take to handle the boat. However, the number is arbitrary since every boat and every skipper is different.

Is 10 mph wind good for sailing?

Ten miles per hour (8.6 knots) of wind is a good wind speed to learn to sail. It is enough wind to fill the sails and provide power for the boat to move, but the control lines will be lightly loaded. The boat will be moving at a leisurely and pleasant pace in most cases. 

It does depend on the boat’s size and direction, however. In light winds like 10 mph, downwind sailing in a big boat will be very slow. So 10 mph is fun for a day on the water and suitable for sailing lessons and dinghy sailing, but not quite enough for quick travel by sailboat if you’re trying to get somewhere.

Is 15 mph wind strong for boating?

In the open ocean, 15 mph (13 knots) of wind is described as a moderate breeze. You can expect small waves of one to four feet to form. This is likely a nice day on the water for sailboats and larger powerboats. Small boats, however, may find the conditions very rough. Of course, local conditions like those found in an inlet could be unsafe for even a bigger boat in a 15 mph wind, so always seek local knowledge when boating in unfamiliar waters. Alternatively, 15 mph wind on a protected body of water like a lake or bay may produce only a light chop and be an ideal wind speed.
