Climate Data

Heating and Cooling Degree Days

Degree days can be used to evaluate the effect of outdoor temperature on energy use. A degree day compares the average outdoor temperature to a standard of 65 degrees Fahrenheit.

Cold days are measured in Heating Degree Days (HDD) where the accumulation in degrees of the daily mean temperature was below 65 degrees F.

Hot days are measured in Cooling Degree Days (CDD) because it would require the use of energy for cooling, the accumulation in degrees of the daily mean temperature above 65 degrees F.
