Where Saint-Apollinaire’s numbers come from

Averages over 30 years, not a forecast.

Normals: ECCC’s normals for Québec Jean Lesage (Airport), 1991–2020, chosen as the nearest location with a full temperature record.
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: Canada’s towns and neighbourhoods of 2,500+ (no city totals, no reserves), each through its own nearest location.
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.
