What signifies a surface wind direction of 180°?

A surface wind direction of 180° indicates that the wind is coming from due south. In meteorological terms, wind direction is expressed as the direction from which the wind originates, rather than the direction it is blowing towards. Therefore, when the wind is reported to be from 180°, it means that it is blowing from the south towards the north.

Understanding wind direction is crucial for flight operations, as it affects takeoff and landing patterns, as well as in-flight performance. Pilots must be aware of wind direction to make informed decisions regarding flight paths and runway selection.
