Where Durham-Sud’s numbers come from

Averages over 30 years, not a forecast.

Normals: the 1991–2020 Canadian Climate Normals at Richmond, the closest ECCC location with twelve months of temperature normals.
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: Canadian towns and neighbourhoods of at least 2,500, each placed by its nearest location (city totals and reserves excluded).
Not on this page: sunshine, which none of ECCC’s 450 locations publishes for 1991–2020, and the town’s own height above sea level, so no figure is adjusted for altitude.
