About this ranking

Total precipitation from January to December, in inches: rain plus the water content of snow and other frozen precipitation. NOAA computes it from its climate divisional dataset (nClimDiv): station readings interpolated onto a 5 km grid and averaged over the area.

Values are area averages, not the reading at one weather station. NOAA revises the last two years every month.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
