Montreal - Extreme Daily Precipitation for Each Year
This page lists the biggest rainstorms or snowstorms of the year in Montreal, Quebec Canada along with the date they occurred. The information answers questions like: When was the last time more than 70 millimetres of precipitation landed on Montreal in a single day? What was the rainiest day of 2017?
The list gives the highest daily precipitation for each year in Montreal 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 1886. During that time the heaviest downpour measured for a single day was 93.5 millimetres (3.7 inches) on November 8, 1996.
Since 1984 the precipitation extremes were observed at Montreal–Trudeau Airport. Before then, the weather station was in downtown Montreal.
