Ranked from NOAA 1991-2020 Climate Normals

Hottest Summers in South Carolina

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.

Maintenance and water are national estimates. Full methodology.
