San Diego - Extreme Daily Rainfall for Each Year





This page lists the heaviest rainfalls and wettest days of each year in San Diego, California. The information answers questions like: When was the last time San Diego got more than 2.5 inches of rain in a single day? What was the heaviest rainfall of 2019?

This page gives the highest daily precipitation for each year in San Diego 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 extremes go back to 1851, with a few years missing data. During that time the biggest one-day rainstorm recorded there dropped 3.34 inches (84.8 millimetres) of water on December 2, 1854.

Since 1940 precipitation was measured at San Diego's International Airport. Before then, the weather station was in downtown San Diego.
