Where Sainte-Mélanie’s numbers come from

Averages over 30 years, not a forecast.

Normals: the Canadian Climate Normals, 1991–2020, at L'Assomption (the closest location with all twelve months of temperatures).
Other locations: precipitation and snowfall come from the nearest location that publishes all twelve months of them, as named above.
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, 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.
