One of the largest regional variations in climate is precipitation. While a number of counties in the Pacific Northwest see over 100 inches of rain per year on average, some counties in the Southwest see less than 10 inches of precipitation in a normal year. A look at NOAA data reveals which cities get the most rain every year.
To determine the rainiest cities in America, Climate Crisis 247 reviewed historical data on monthly precipitation from the NOAA. County seats were ranked based on average monthly rainfall amounts from 1924 to 2023. All data is at the county level.
