Where Saint-Flavien’s numbers come from

Averages over 30 years, not a forecast.

Normals: the Canadian Climate Normals, 1991–2020, at Québec Jean Lesage (Airport) (the closest location with all twelve months of 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: every Canadian town and neighbourhood of 2,500 or more, each read from its own nearest location; city totals and reserves are left out.
Not on this page: sunshine (no 1991–2020 normals exist for it) and any altitude adjustment, since there is no elevation for the town itself.
