The Relative Humidity and Winds map displays the current relative humidity, displayed in percent (%), at each Mesonet site, as well as the average wind conditions across Oklahoma. Relative Humidity is the measure of the water vapor content of the air at a given temperature. The arrows, known as wind vectors, indicate both the average wind speeds (in miles per hour) at 10 meters (33 feet) across Oklahoma and the average direction the wind is blowing toward. This map is updated every 5 minutes.
