Definition

Sum over January to December of the degrees by which the daily mean temperature exceeds 65°F, a measure of cooling demand. NOAA estimates monthly values from nClimDiv temperatures and weights areas by population (2010 Census).

NOAA publishes these for operational monitoring; they can differ from official degree day publications.
