Wind direction is reported by the

degrees. For example, a wind coming from the south is given as 180 one from the east is 90 degrees.
A variety of instruments can be used to measure wind direction, such as the
and . Both of these instruments work by moving to minimize air resistance. The way a weather vane is pointed by prevailing winds indicates the direction from which the wind is blowing. The larger opening of a windsock faces the direction that the
its tail, with the smaller opening, points in the direction the wind is blowing.
Modern instruments used to measure wind speed and direction are called
and , respectively. These types of instruments are used by the wind energy industry, both for
In situations where modern instruments are not available, an index finger can be used to test the direction of wind. This is accomplished by wetting the finger and pointing it upwards. The side of the finger that feels "cool" is (approximately) the direction from which the wind is blowing. The "cool" sensation is caused by an increased rate of evaporation of the moisture on the finger due to the air flow across the finger, and consequently the "finger technique" of measuring wind direction does not work well in either very humid or very hot conditions. The same principle is used to measure the
(a more accurate instrument than the human finger).
Another primitive technique for measuring wind direction is to take a pinch
the direction that the grass falls is the direction the wind is blowing. This last technique is often used by golfers because (in addition to grass being convenient and plentiful on golf courses) it allows them to gauge the strength of the wind as well.
