Saint John NB - Extreme Daily Precipitation for Each Year

This page lists the biggest rainstorms or snowstorms of the year in Saint John, New Brunswick Canada along with the date they occurred. The information answers questions such as: What was the rainiest day of 2019?

The list gives the highest daily precipitation for each year in Saint John 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 1871, with a few recent years missing data. During that time the heaviest downpour measured for a single day was 154.4 millimetres (6.08 inches) on November 13, 1975.

Since 1952 the precipitation extremes were observed at the Saint John Airport. Before then, the weather station was near the city centre.
