Methodology · NOAA precipitation normals
Annual precipitation from 30-year climate normals.
The ranking value is NOAA 1991-2020 annual precipitation normal in inches. CONUS rows use NOAA's nClimGrid monthly gridded normals; Alaska, Hawaii, and non-CONUS rows use the nearest available station path recorded by the climate pipeline.
Rows are limited to cities with 2024 Census PEP population of at least 5,000 and a non-null annual precipitation normal. Ranks use standard competition ranking, so exact ties share the same rank.
Precipitation is not the same as flood risk. This page does not include drainage, elevation, riverine exposure, hurricanes, storm surge, wildfire, drought, or property-level hazard data.
