Boston - Extreme Daily Precipitation for Each Year





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

This page gives the highest daily precipitation for each year in Boston 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 extremes go back to 1893. Since 1937 precipitation was measured at Boston's Logan International Airport. Before then, the weather station was in downtown Boston.

During that time, the heaviest downpour recorded for a single day there was 7.06 inches (179.3 millimetres) on August 19, 1955.
