Where Eau Claire’s numbers come from

Averages over 30 years, not a forecast.

  • Normals: the Canadian Climate Normals, 1991–2020, at Calgary (Airport) (the closest location with all twelve months of temperatures).
  • Comparisons: every place of 2,500+ in Canada but the city hubs and the reserves, each on its nearest ECCC 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.
