Calgary - Extreme Daily Precipitation for Each Year

This page lists the biggest rainstorms or snowstorms of the year in Calgary, Alberta Canada along with the date they occurred. The information answers questions like: When was the last time more than 60 millimetres of precipitation landed on Calgary in a single day? What was the rainiest day of 2019?

The list gives the highest daily precipitation for each year in Calgary 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 were observed at Calgary International Airport and go back to 1885. During that time the heaviest downpour measured for a single day was 95.3 millimetres (3.75 inches) on July 15, 1927.
