AVERAGE MONTHLY DEW POINT TEMPERATURE (F)
Dew point is the temperature at which air becomes saturated when cooled without addition of moisture or change of pressure. Any
further cooling causes condensation; fog and dew are formed in this way.
Based on daily average dew point temperatures from reporting ASOS locations.
Data is preliminary and may contain errors.
