Dayton - Extreme Daily Precipitation for Each Year





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

The list gives the highest daily precipitation for each year in Dayton 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 1934. During that time the most precipitation - measured as rain or melted snow - to arrive in one day was 4.16 inches (105.7 millimetres) on January 21, 1959.

Since 1948 the precipitation extremes were observed at Dayton International Airport. Before then, the weather station was in downtown Dayton.
