Where Windsor’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Richmond, 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 towns and neighbourhoods of 2,500+ across Canada, each on its nearest normals location, without the city totals or the reserves.
- Not on this page: sunshine, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
