Denver - Extreme Daily Precipitation for Each Year





This page lists the biggest rainstorms or snowstorms of the year in Denver, Colorado along with the date they occurred. The information answers questions like: When was the last time more than five inches of precipitation landed on Denver in a single day? What was the rainiest day of 2018?

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

These precipitation extremes go back to 1921, with one year missing data. During that time, the heaviest downpour recorded for a single day was 6.47 inches (164.3 millimetres) on September 13, 2013.

Since 1948 the storms were measured at Denver's Stapleton neighborhood. Before then, the weather station was in downtown Denver.
