Los Angeles - Extreme Daily Rainfall for Each Year





This page lists the heaviest rainfalls and wettest days of each year in Los Angeles, California. The information answers questions like: When was the last time Los Angeles got more than five inches of rain in a single day? What was the heaviest rainfall of 2018?

This page gives the highest daily precipitation for each year in Los Angeles 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 in downtown Los Angeles and go back to 1921, with just a few years missing data. Since then the biggest one-day rainstorm recorded there dropped 5.71 inches (145 millimetres) of water on January 26, 1956.
