Where Trenton’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Caribou Point, 1991–2020, chosen as the nearest location with a full temperature record.
- Other locations: a location missing months of precipitation or snow is filled from the nearest that has them all, never mixed month by month.
- 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.
