Where Shefford’s numbers come from

Averages over 30 years, not a forecast.

  • Normals: the closest ECCC location with twelve months of temperature normals, Granby, 1991–2020.
  • Comparisons: Canadian towns and neighbourhoods of at least 2,500, each placed by its nearest location (city totals and reserves excluded).
  • 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.
