Where Château-Richer’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Saint Michel from ECCC’s climate data site, the nearest location with every month of temperature.
- Other locations: where a location publishes no full year of precipitation or snowfall, the nearest one that does supplies it, named beside those figures.
- Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
- Not on this page: sunshine, which none of ECCC’s 450 locations publishes for 1991–2020, and the town’s own height above sea level, so no figure is adjusted for altitude.
