Where Westmorland’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Nappan from ECCC’s climate data site, the nearest location with every month of temperature.
- 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: all Canadian places of 2,500 or more except city totals and reserves, each read the same way.
- Not on this page: sunshine, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
