Where Selkirk’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Winnipeg Richardson (Airport) from ECCC’s climate data site, the nearest location with every month of temperature.
- Comparisons: a pool of Canadian towns and neighbourhoods of 2,500 or more, read alike; whole cities and reserves stay out of it.
- Not on this page: sunshine, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
