Where Gananoque’s numbers come from

Averages over 30 years, not a forecast.

  • Normals: the 1991–2020 Canadian Climate Normals at Kingston, the closest ECCC location with twelve months of temperature normals.
  • Other locations: where a location publishes no full year of precipitation or snowfall, the nearest one that does supplies it, named beside those figures.
  • 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, absent from every 1991–2020 location, and an altitude correction, for want of the town’s own elevation.
