Averages over 30 years, not a forecast.
- Normals: the closest ECCC location with twelve months of temperature normals, Kamloops, 1991–2020.
- 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.
