- Definition: Mean air temperature from January to December, in degrees Fahrenheit: the average of the 12 monthly mean temperatures. NOAA computes it from its climate divisional dataset (nClimDiv): station readings interpolated onto a 5 km grid and averaged over the area.
- Note: Values are area averages, so a county with mountains and valleys has one value for very different local climates. NOAA revises the last two years every month.
