Key West - Extreme Daily Rainfall for Each Year





This page lists the heaviest rainfalls and wettest days of each year in Key West, Florida. The information answers questions like: When was the last time Key West got more than half a foot of rain in a single day? What was the heaviest rainfall of 2019?

This page gives the highest daily precipitation for each year in Key West and the date that it happened. A date with a plus sign beside it means the same amount of rain also fell on at least one other day earlier that year.

These precipitation extremes were measured at Key West International Airport and go back to 1948, with a few years missing data. Since then the biggest one-day rainstorm recorded there dropped 22.75 inches (577.9 millimetres) of water on November 11, 1980.
