St. John's NL - Extreme Daily Precipitation for Each Year





This page lists the biggest rainstorms or snowstorms of the year in St. John's, Newfoundland Canada along with the date they occurred. The information answers questions such as: What was the rainiest day in 2019? And how much rain fell on the wettest day of 1874?

The list gives the highest daily precipitation for each year in St. John's 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 1874, with some years missing data. During that time the heaviest downpour measured for a single day was 173.2 millimetres (6.82 inches) on August 29, 1876.

Since 1942 the precipitation extremes were observed at the St. John's Airport. Before then, the weather station was in downtown St. John's.
