Where Cartier’s numbers come from

Averages over 30 years, not a forecast.

Normals: the 1991–2020 Canadian Climate Normals at Portage Southport, the closest ECCC location with twelve months of temperature normals.
Other locations: precipitation and snowfall come from the nearest location that publishes all twelve months of them, as named above.
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, 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.
