How To Read Wind Direction Arrows On Weather Maps?

Wind direction arrows on a weather map represent the direction from which the wind is blowing. The arrow points in the direction of the wind, while the arrow’s tail represents the wind’s origin. The length of the arrow corresponds to the wind speed, with longer arrows indicating stronger winds. For example, an arrow pointing to the east indicates a wind blowing from the east to the west. It is important to note that wind direction is reported as the direction from which the wind is blowing, not the direction it is moving towards. Understanding wind direction is important for various outdoor activities and planning for severe weather events.

Wind direction on a weather map is typically indicated by symbols called wind barbs or wind arrows. Wind barbs consist of a line with “flags” or “feathers” that indicate the direction and speed of the wind. The orientation of the line shows the direction of the wind, while the number and shape of the flags or feathers indicate the wind speed. For example, a line pointing to the north with three feathers on the right side indicates a wind blowing from the south with a

Weather maps often display arrows that indicate the direction of the wind. In addition, the arrows indicate the typical clockwise movement around high-pressure systems and anti-clockwise movement around low pressure.

The arrows also join places that have equal air pressure (isobars). These isobars are often printed with letters on a map to help you identify the difference.


Wind direction arrows are a common feature of weather maps, and they can confuse newcomers to meteorology. They are used to show where the wind is coming from and how strong it is, which is important for determining what outdoor activities are possible in a given area.

A compass rose is the most basic and familiar way to read a wind direction. This graph shows the prevailing wind direction and speed at a certain location based on several years of weather observations (also called weather history).

You can use a compass rose to identify wind directions in degrees or radians, but it’s best to convert between these readings before making ad hoc estimates. You can learn how to do this by checking out our article on converting degrees into compass directions.

Another way to determine the wind direction is by examining the isobars on a map. These lines connect points with the same atmospheric pressure, and the wind moves counterclockwise around low-pressure areas and clockwise around high-pressure areas.

In some situations, the isobars can line up with the wind direction arrows; in other cases, they are almost at right angles to them. This is because the wind may be moving from one direction, then changing to a different one as it passes through an isobar.

On a wind map, isobars are drawn simultaneously with the wind observations at MetService stations. The arrows show the wind’s direction and indicate which parts of the map are prone to different kinds of wind, such as gusty winds or dry weather.

The isobars can also be a helpful tool to determine the wind’s speed. For example, a wind barb vector pointing to 135 deg means that the air is blowing from the southeast. A wind barb at 270 deg indicates the air blowing from the west.

Wind direction arrows are usually colored – blue for an east wind, red for a north wind, and green for a south wind. However, these colors are reversible, so you can switch between them to see what’s happening at any point on the map.


If you have ever seen a weather map, you have probably noticed that the arrows are plotted to indicate wind direction. These arrows are typically based on a standard 16-point compass rose, which has been divided into four basic directions: North (N), South (S), East (E), and West (W).

This idea is called a wind rose because it shows prevailing winds at a particular location based on weather history. This is a pretty precise concept because it uses statistics from many years of meteorological observations.

To make these graphs more accurate, people divided the original cardinal directions into four additional intercardinal directions: Northeast (NE), Southeast (SE), Northwest (NW), and Southwest (SW). This way, they could be better identified with a human-designed coordinate system.

The resulting eight principal directions are still as confusing as the original four. Most of the time, they aren’t even useful for the weather!

Generally, a northerly wind blows from the north to the south; an easterly wind blows from the east to the west.

One way to determine a wind direction is by reading the angle of the arrow. This angle is expressed in degrees, and the longer the arrow, the more powerful the wind.

Another way to determine a wind direction is by checking the wind speed. The wind speed is usually given in units of “knots” or a nautical mile per hour.

Some weather stations also use a wind barb to show the wind direction on their map, which is similar to an arrow but points into the wind instead of outwards. However, it can be harder to read a wind barb, so you may want to check out our article on how to read a wind barb.

On a traditional map, the north is at the top, and the west is at the left. This is a very common arrangement. However, it might have been the other way around on older maps!

This is a little confusing, but not nearly as bad as it sounds. This is because a typical weather vane shows the opposite – the arrows point into the wind rather than outwards.


A wind vane is a great tool for learning about the weather because it can show you which direction is blowing. These are generally made of two parts: one shaped like an arrow that turns into the wind and a wider part that catches the breeze.

A well-made arrow-shaped wind vane is a lot of fun to use. They are also useful for identifying the direction of a breeze and the speed at which it is moving.

You may have heard of a wind rose, a graph that displays prevailing winds at a given location based on several years of data from meteorological observations (also known as weather history). A compass is a classic device for determining cardinal directions.

However, the arrow on the wind vane is the show’s star since it shows the most significant directional change in your locale. A wind vane is an incredibly effective way to display this information, so it’s important to have one handy when the weather changes rapidly.

When looking for the best way to display the wind direction on your property, consider using a wind vane, which can be purchased from any hardware store. These are designed to be very accurate and reliable.

Another good wind direction indicator is isobars, which connect points with similar atmospheric pressure. These lines are usually oriented clockwise or counterclockwise, depending on their placement.

To get the arrow on the wind vane right, you should blow on it to ensure it spins freely. This can be done by placing the vane in a sunny spot and holding a paper plate in front of it.

If you’re unsure which wind direction is correct for your location, consult with the WRAL Weather team for more assistance. The team is always on hand to help you understand the windy weather in your area!


Wind direction is a very important topic in meteorology and weather forecasting. For example, if you do an outdoor activity, such as skiing, hiking, or cycling, you will want to know where the wind is blowing.

The most basic way to determine the wind direction is by using a compass. This device will show you four directions: North, South, East, and West.

To read a compass, simply place it in the center of a paper plate and turn it until that line matches up with the arrow that is pointing to the north.

This arrow will be a representation of the wind that is blowing in your area. If you look at a map, it is most likely going to be a representation of a 500 mb wind.

In addition to a compass, you can also use isobars to figure out the direction of the wind. Isobars are map lines connecting points with the same atmospheric pressure.

Whenever there is an area of high or low pressure, the wind will move clockwise or counterclockwise around the isobars. The surface wind leaks across the isobars towards the low-pressure area.

The length of the arrows on these isobars will tell you how strong the wind is and the direction it is moving in. The longer the arrow, the stronger the wind.

You can also learn the wind direction by looking at the arrows on the plotted vectors. These arrows point in the direction of the wind and are often color-coded to indicate intensity.

Looking at the above image, you can see that the wind is mainly blowing from west to east. This is because the wind is moving along the arrows plotted as black arrows.

Another useful tool for determining the wind direction is a wind rose. This graph was designed to show the prevailing wind direction and speed at a particular location over time.

You can find these tools on many weather maps, which often have other information, such as precipitation forecasts. These tools can help you plan your activities and maximize your day!

The wind is one of the most important factors in predicting current weather and determining future forecasts. This is because it transports moisture and temperature from one area to another, affecting weather patterns.

Knowing the wind direction is a must when outdoors, especially for archers. This article will look at six (un)orthodox ways to check your wind direction.

Identifying Wind Directions

One of the most important aspects of wind is its direction. It can be critical for sailing, flying a kite, and deciding where to put a windmill. Fortunately, there are many ways to determine the wind’s direction. Some of these methods involve simple instruments that are easy to use and very effective.

For example, you could hold your finger in the air and feel the side that gets cool quickly. This method works great in dry conditions and can detect even faint breezes.

Special instruments can also measure the wind’s direction, such as an anemometer. These devices can accurately tell whether the wind is blowing from the east, west, or north.

Another simple way to identify the wind’s direction is to use a compass rose or a weather vane. These instruments are easy to find and can be extremely helpful when determining a windstorm’s direction.

A compass rose can be found at most hardware stores and will display a variety of directional symbols that can help you figure out the current wind direction. These symbols can be confusing initially, but with practice, you’ll know what they mean and how to read them.

For example, if you see an arrow that points to 135deg on the bottom-right quadrant of the chart, it indicates that the wind is blowing from the southeast. Similarly, if you see a 270deg wind barb, it indicates that the wind is coming from the west.

These symbols can also be used to calculate the speed of the wind. For example, an incoming wind with a barbed end at a right angle to the arrow indicates a windspeed of 60 knots. This is the equivalent of 69 miles per hour.

You can use this information to plan your activities and avoid dangerous conditions. For example, if you want to sail at night, you must know what the wind is doing to avoid hitting rocks or other obstacles.

Identifying Wind Speeds

Wind direction is a critical weather measurement that meteorologists use to predict storms and changing conditions. It is also important for many sports and outdoor activities, such as sailing or flying a kite.

Fortunately, there are several ways to determine wind direction without expensive and complicated equipment. For example, you can feel the air, watch as it moves a body of water, or use specialized tools like a wind vane or windsock.

Blow on the vane to determine the wind’s direction with a wind vane and look for an arrow pointing in the desired direction. The arrow will usually have two parts, one shaped like an arrow that turns into the wind and another wider to catch the breeze.

The arrow is also known as the “head,” and the tail is called the “tail.” If the arrow points toward the east, the wind comes from that direction.

Some other simple methods can help you determine wind direction, including putting your finger in your mouth and observing how it blows. You can also feel the air around your face and turn slowly from side to side to get a rough idea of which way the wind is blowing.

You can even use a compass to see how the wind is going. The wind is always moving clockwise when it is around a high-pressure system and anti-clockwise when it is around a low-pressure weather system.

If you are sailing, knowing your wind speed and direction is important to control your sails and keep your boat from getting blown out of the water. Knowing the wind’s direction is especially important when sailing a long distance, such as across an ocean or lake.

When determining your wind speed, you can use the Beaufort Scale to estimate the wind coming from a given direction. The scale is not as precise as other methods, but it’s still useful for estimating wind speed.

You can read wind barbs on a weather map to get a more visual representation of the wind’s direction. These diagrams show the speed of the wind from a particular direction in a simple format that is easy to understand. You can find these diagrams on a variety of weather maps and websites.

Identifying Wave Directions

Wind Direction Arrows are a great way to learn wind direction. They are often found in malls, alleys, schools, restaurants, etc.

These arrows are usually very small and have one wide end to catch the wind. The other end of the arrow spins on a rod and points into the wind so that you can see which direction the wind is coming from.

Getting a feel for the wind direction is essential to read waves, so you must know what you are looking at when you’re in the water. This will give you a better chance of spotting the right waves forming so that you can surf them effectively and efficiently.

In addition to learning how to read waves, it’s also a good idea to learn how to determine wind speed. This will help you predict the best time to go surfing and the most likely wave type that will break.

You can also check out the wind rose to better understand how the winds are blowing in your area. This unique graph shows the prevailing wind direction in the area and includes information on surf swell directions, which is perfect for those looking to go surfing.

There are several ways to identify a wave’s direction, but the most accurate is looking at the wave’s crest. A wave’s crest is the highest point on the wave’s surface, and it usually has a curve to it, making it easy to tell which direction the wave is going in.

Once students grasp how to read a wave, it’s helpful to have them perform a “water wave demonstration.” Show them how to draw a line that goes up and down, and ask them to share what images they have when they think about a wave.

Then, have them close their eyes and picture all the different types of waves out there. Many students will describe waves in the water, earthquakes, sound, light, and even a curved line that goes up and down.

Identifying Gusts

Wind Direction Arrows, also known as Gust Arrows, are a way to indicate the direction of the wind on a weather map. They look similar to a weather vane, except that they point opposite where the wind is blowing.

These arrows typically appear in a circle on a weather chart and are usually accompanied by a contour plot of wind speed for their location. They show the strongest winds, or gusts, in a given area at a particular time.

The longer the arrow, the stronger the wind. For example, a short arrow might be used to indicate 5 knots of wind, while a long one might be used to indicate 50 knots.

However, these symbols are not always accurate at the surface. In most locations, sustained winds rarely reach the speeds listed in these arrows. Instead, they’re more often used to represent “gusts” of wind, characterized by a sudden and brief increase in speed.

Weather services often report Gusts in various ways, such as the average number of guests per second or the maximum wind speed at any time during a specific period. These are based on the air’s turbulence, which can vary drastically.

This can cause a large drag on an arrow, affecting its trajectory. For example, if you shoot a 230 fps arrow into a 15 mph headwind, its relative speed would be 252 fps (a 10% increase in effective speed), causing it to have 20% more drag than it would on a calm day.

Even a slightly angled breeze can be a problem, and this effect is particularly difficult to deal with on a small-drag arrow like a crossbow. However, a 90-degree side wind is a much more challenging situation, as it hits the full length of the shaft and, fletching, a sail.

These effects can be very confusing, but it’s important to remember that headwinds and tailwinds don’t always work the same. For example, a headwind on a port tack can result in a windward lift, but a starboard tack tailwind can shift the windward.


What do wind direction arrows on weather maps represent?

Wind direction arrows on weather maps indicate the direction that the wind is blowing from, not the direction it is going towards.

How do I read wind direction arrows on a weather map?

Wind direction arrows are typically represented as small lines with triangular “feathers” on one end. The feathered end points in the direction that the wind is blowing from.

What do the different lengths of wind direction arrows mean?

The length of a wind direction arrow indicates the strength of the wind. Shorter arrows represent weaker winds, while longer arrows represent stronger winds.

What do the different colors of wind direction arrows mean?

The colors of wind direction arrows on weather maps can vary depending on the map legend or key. In general, blue or green arrows represent lower wind speeds, while red or orange arrows represent higher wind speeds.

Can wind direction arrows indicate wind gusts?

Wind direction arrows on weather maps generally represent the average direction and speed of the wind over a given period of time (usually several hours). They do not necessarily indicate wind gusts, which can be much stronger and more localized.

How can I use wind direction arrows to predict weather conditions?

Wind direction arrows can be useful for predicting weather conditions, as wind patterns can provide clues about the movement of weather systems and the likelihood of precipitation or other weather events. For example, winds blowing from the south or southeast in the United States can indicate the approach of a warm front and potentially stormy weather.
