Duluth - Extreme Daily Precipitation for Each Year





This page lists the biggest rainstorms or snowstorms of the year in Duluth, Minnesota along with the date they occurred. The information answers questions like: When was the last time more than four inches of precipitation landed on Duluth in a single day? What was the rainiest day of 2019?

The list gives the highest daily precipitation for each year in Duluth 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 1909, with a few years missing data. During that time the heaviest downpour measured for a single day was 4.28 inches (108.7 millimetres) on August 9, 1939.

Since 1948 the precipitation extremes were observed at Duluth International Airport. Before then, the weather station was at Superior WI.
