Averages over 30 years, not a forecast.
- Normals: the 1991–2020 Canadian Climate Normals at Winnipeg Richardson (Airport), the closest ECCC location with twelve months of temperature normals.
- 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: hours of sunshine, missing from the 1991–2020 normals, and a height correction: the town has no elevation on file.
