Where Saint-Sauveur’s numbers come from

Averages over 30 years, not a forecast.

Normals: Environment and Climate Change Canada’s 1991–2020 normals, Ste-Foy (U. Laval): the nearest of its locations with every month’s temperatures.
Other locations: ECCC blanks a month that fails its completeness rule, so the precipitation or snowfall here comes from the next location with all twelve months.
Comparisons: the towns and neighbourhoods of 2,500+ across Canada, each on its nearest normals location, without the city totals or the reserves.
Not on this page: hours of sunshine, missing from the 1991–2020 normals, and a height correction: the town has no elevation on file.
