For example, a northerly wind blows from the north to the south . Wind direction is usually reported in cardinal directions or in azimuth degrees . Wind direction is measured in degrees clockwise from due north and so a wind coming from the south has a wind direction of 180 degrees; one from the east is 90 degrees .
