Ranked from NOAA 1991-2020 Climate Normals
Highest Cooling Demand in Maine
Cooling degree days are the mirror of heating degree days: how far and how long the temperature sits above 65°F. In the counties at the top of this list, cooling is the largest single line on the summer electricity bill. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year.

Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
