What this measures

The average daily high temperature in June, July and August, in degrees Fahrenheit, across the whole county or state. It shows how hot summer afternoons are. Source: NOAA NCEI nClimDiv.

For most measures, a national ranking mostly sorts places by income and by how urban they are. Each county’s own page compares it with the 50 counties most like it instead, which is often the fairer view.
