The warmest part of a July day comes in at 25.1°C on average. The seasons are far apart: from a winter night to a summer afternoon the average spans 39°C. Counting rain and snow together, it is wetter than 80% of Canadian towns. Ice scrapers and block heaters earn their keep on roughly 145 days a year at 0°C or below.
Borrowed figures: Saint-Maurice has no normals station, so these come from Trois-Rivières, 12 km south.

- Normals: Environment and Climate Change Canada’s 1991–2020 normals, Trois-Rivières: the nearest of its locations with every month’s temperatures.
- Comparisons: Canada’s towns and neighbourhoods of 2,500+ (no city totals, no reserves), each through its own nearest location.
- Not on this page: a sunshine figure (ECCC published none for 1991–2020) and any lapse-rate correction for height, as the town has no elevation here.
