The wind forecast (along with temperature) can help in deciding what to wear to stay warm or cool. However, higher winds can make observing or astrophotography difficult, especially with larger telescopes.
Astrospheric processes hourly wind details from the Canadian RDPS.
Along with speed, Astrospheric also shows the direction of the wind. The triangle within a hour's wind circle points in the direction the wind is heading. It's easiest to think of the circle as a compass; when the triangle points towards the top, then the wind is blowing towards the North.
