Sources

Where Dufferin Grove’s numbers come from

Averages over 30 years, not a forecast.

  • Normals: Environment and Climate Change Canada’s 1991–2020 normals, Toronto (City): the nearest of its locations with every month’s temperatures.
  • Other locations: precipitation and snowfall come from the nearest location that publishes all twelve months of them, as named above.
  • Comparisons: the 2,500-plus towns and neighbourhoods of Canada, each read from its closest normals location; whole cities and reserves aren’t counted.
  • 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.
