Where Notre-Dame-du-Portage’s numbers come from

Averages over 30 years, not a forecast.

  • Normals: ECCC’s normals for Rivière-du-Loup/St-Antonin, 1991–2020, chosen as the nearest location with a full temperature record.
  • Other locations: where a location publishes no full year of precipitation or snowfall, the nearest one that does supplies it, named beside those figures.
  • Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
  • 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.
