What this measures

The average nightly low in winter, in degrees Fahrenheit, across the whole county or state. Winter here means December of the year before, then January and February. So the winter of 2024 to 2025 is listed under 2025. 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.
