Where L'Isle-Verte’s numbers come from

Averages over 30 years, not a forecast.

Normals: the 1991–2020 Canadian Climate Normals at Rivière-du-Loup/St-Antonin, the closest ECCC location with twelve months of temperature normals.
Other locations: a location missing months of precipitation or snow is filled from the nearest that has them all, never mixed month by month.
Comparisons: all Canadian places of 2,500 or more except city totals and reserves, each read the same way.
Not on this page: sunshine, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
