"Winds from 315 degrees" indicates which direction?

Winds described as coming from 315 degrees indicate a direction that is typically associated with the northwest quadrant on a compass. In aviation and meteorological data, wind direction is given as the direction the wind is coming from, measured in degrees from true north.

At 315 degrees, you are looking at a wind that is blowing from the northwest, specifically at a 45-degree angle measured between north (0 degrees) and west (270 degrees). This means that if you were standing at the source of the wind, you would feel it coming from the northwest towards the southeast.

Other directions listed, such as southwest, northeast, and east, do not accurately correspond to the 315-degree measurement. For instance, winds from the southwest would be around 225 degrees, northeast winds would be from 045 degrees, and east winds would be around 090 degrees. Thus, the indication of wind from 315 degrees unmistakably corresponds to a northwest direction.
