Where Innisfail’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Red Deer 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, 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.
