GPTR Rank - Lower "Total Heating/Cooling Degree Days" translates to lower home
heating and cooling costs.
Heating Degree Days (HDD)
       Measure of how cold it is relative to 65 degrees. Relates temperature to the demands
       of a/c. Calculated as the number of degrees that a day's average temperature
       (high + low / 2) is below 65.
       Example:  On June 20 in Bellingham, the day's high was 72 and low was 50. The
                        average temperature was 61 meaning June 20 had 4 heating degree days.
Cooling Degree Days (CDD)
       Measure of how hot it is relative to 65 degrees. Relates temperature to the demands
       of heating a residence. Calculated as the number of degrees that a day's average
       temperature (high + low / 2) is above 65.
HDD and CDD can vary widely depending upon your location:
HDD CDD
Fairbanks, AK 13,542 45 Cold climate
Hilton Head, SC 2,119 2,012 Temperate climate
Phoenix, AZ 1,125 4,189 Hot climate
