Seattle - Extreme Daily Precipitation for Each Year





This page lists the biggest rainstorms or snowstorms of the year in Seattle, Washington along with the date they occurred. The information answers questions like: When was the last time more than three inches of precipitation landed on Seattle in a single day? What was the rainiest day of 2017?

This page gives the highest daily precipitation for each year in Seattle 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 records go back to 1894, with just one year missing data. During that time the heaviest downpour measured for a single day was 5.02 inches (127.5 millimetres) on October 20, 2003.

Since 1948 the precipitation extremes were observed at Seattle—Tacoma International Airport. Before then, the weather station was at University of Washington.
