- Normals: the 1991–2020 Canadian Climate Normals at Edmonton (Airport), the closest ECCC location with twelve months of temperature normals.
- 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.
