Where Saint-Gilles’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Scott from ECCC’s climate data site, the nearest location with every month of temperature.
- 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.
