Where Saint-Basile-le-Grand’s numbers come from

Averages over 30 years, not a forecast.

Normals: ECCC’s 1991–2020 Canadian Climate Normals for L'Acadie, the nearest location with a full year 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: a pool of Canadian towns and neighbourhoods of 2,500 or more, read alike; whole cities and reserves stay out of it.
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.
