February Heating Degree Days

A heating degree day (HDD) is a measure of how cold a location is. It’s derived by comparing the average outdoor temperature to a baseline of 65 degrees. More extreme cold temperatures result in a higher number of HDDs, which typically translate to an increased demand for space heating by energy consumers.

The below data sets detail the number of HDDs that occurred in the month of February during the past 3 years, as well as the month’s 10-year average, broken down by Census Division.
