Ranked from NOAA 1991-2020 Climate Normals
Hottest Summers in Michigan
Average daily high in the hottest month of the year, by county. Read it next to the cooling degree days in the same row: the two together are what the summer electricity bill is actually made of. 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.
