Cincinnati - Extreme Daily Precipitation for Each Year





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

The list gives the highest daily precipitation for each year in Cincinnati 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 1916. During that time the heaviest downpour measured for a single day was 5.21 inches (132.2 millimetres) on March 9, 1964.

Since 1949 the precipitation extremes were observed at Cincinnati/Northern Kentucky International Airport. Before then, the weather station was near downtown Cincinnati.
