What is the best way to average wind direction? Wind Map | NOAA Climate.gov For example, if you have a wind blowing to the east (at $0^\circ$) at 10 mph for half the time and to the north (at $90^\circ$) at 2 mph half the time, the average probably shouldn't be $45^\circ$ but something much closer to $0^\circ$. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
