Knowing wind direction, or the direction that the current of air is bravado from, can exist imperative in several instances. For example, if you are sailing, flight a kite, or deciding where to place a windmill, the air current direction volition be your well-nigh of import piece of information. Luckily, there are several means to determine wind direction. You can experience the current of air, lookout man equally it moves a trunk of water, or employ specialized equipment to observe its direction.

1
Moisture your finger. Stick your alphabetize finger down in h2o to get it wet. Concur your finger up and away from your body. The side of your finger that gets absurd is the side that the wind is blowing from.^[ane]
- If you put your finger in your oral fissure to go it wet (which works well when there is no water nearby), be sure that you lot get information technology wet all the way around.

Scout the ripples. Look for a nighttime pool of h2o. Watch how the ripples flow over the water. These ripples are formed by the current of air pushing the water and breaking its surface. The ripples volition flow in the management of the wind.^[6]
- If you're non most a large body of water, put out a pan or bucket of water. You should still able to run across the wind rippling on the surface.
2

Await out to a horizontal aeroplane. Every bit you are looking out over the h2o, observe a horizontal (left to right) stretch of water that is roughly 15 yards (xiv yard) broad. Observing the direction of this strip is a more authentic representation of wind direction than watching individual ripples. The strip will travel the same management that the air current is blowing.^[seven]
3
Determine wind patterns by watching the water from a boat. When detecting subtle variations in current of air management, such as on a sailboat, y'all should be looking forward and back. Lookout how the wind is affecting the water in front of you lot by focusing on a horizontal stretch of ripples in front of you. Too, glance dorsum backside you to run across how the air current is behaving there. This allows you lot to observe changes in the wind directly rather than waiting for your gunkhole to react.^[viii]
- Whether yous are looking forward or back, you will use the same technique of identifying a horizontal stretch and observing the ripples.

Tie tassels to an object. Perhaps the simplest of all wind monitoring devices is a tassel or piece of string. Necktie a lightweight cord or tassel to an object and let it dangle. Equally the current of air blows, the string or tassel will accident right along with it. The wind is bravado in the management that the tassel points.^[9]
ii

Make an anemometer. You can make devices, such equally an anemometer, to measure wind direction. These can be simple homemade devices, or circuitous precision tools. Either way, the anemometer cups the current of air and spins, indicating both the direction and intensity of the wind.^[10]
3
Hang a wind sock. A current of air sock is a device that has one big opening attached to a pole or base. The opening on the other finish is much narrower. Equally the current of air blows through the sock, it will plow to indicate in the direction that the current of air is blowing.^[xi]
- Yous tin also hang up flags to get a sense of where the wind is blowing.^[12]
iv
Install a weather vane. A weather vane is designed to point straight into the wind. I side of the weather condition vane will exist a narrow, pointed end (commonly resembling the tip of an arrow). The other end is made wider to catch the wind. Equally the current of air blows, you lot can see the arrow point directly into the wind. You must put the weather vane on a sturdy base or pole.^[13]
- A lot of boats have an pointer installed on top of the mast—this is called a Windex, and information technology flips in the direction that the wind is coming from.^[14]
