Edmonton - Extreme Daily Precipitation for Each Year
This page lists the biggest rainstorms or snowstorms of the year in Edmonton, Alberta Canada along with the date they occurred. The information answers questions like: When was the last time more than 50 millimetres of precipitation landed on Edmonton in a single day? What was the rainiest day of 2019?
The list gives the highest daily precipitation for each year in Edmonton 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 1883, with just a few years missing data. During that time the heaviest downpour measured for a single day was 114 millimetres (4.49 inches) on July 31, 1953.
Since 1994 the precipitation extremes were observed at Edmonton International Airport. Before then, the weather station was at Edmonton Municipal Airport.
