Where Turner Valley’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Calgary (Airport), 1991–2020, chosen as the nearest location with a full temperature record.
- Comparisons: Canada’s towns and neighbourhoods of 2,500+ (no city totals, no reserves), each through its own nearest location.
- 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.
