Ranked from NOAA 1991-2020 Climate Normals

Highest Cooling Demand in Louisiana

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.

Where does yours land? Every county in America is somewhere on this scale, including the one you live in.

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.
