How to Read a Windsock
A windsock is a common weather instrument used to specify wind direction and wind speed. It is a conical shaped tube that is open on both ends to allow wind to pass freely through and is usually made out of a textile that is both lightweight and strong. These instruments (also known as wind sleeves) are used primarily at airports to help pilots make safe landings and at chemical plants where there may be a risk of dangerous gaseous leaks. They can also be made at home as a craft with children and are not difficult to read.

1
Purchase a windsock from a store that sells weather instruments or order one online. Place the windsock outdoors in an area that is free from obstructions and clearly visible from a window.
-
2
Observe the direction that the windsock is blowing on a windy day. Wind direction is opposite of the direction that the sock points. Use a compass to find out the exact point from which the wind is originating. A windsock that is blowing to the east indicates a westerly wind while one that is blowing to the north indicates a southerly wind.

Take note of the angle of the windsock (compared to the mounting pole or mast) as the wind blows. This indicates wind speed. A droopy sock indicates low winds, while a sock that is flying in a horizontal fashion indicates high winds.
