Where Argyle’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for London 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: 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 (no 1991–2020 normals exist for it) and any altitude adjustment, since there is no elevation for the town itself.
