Where Doon South’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Kitchener/Waterloo, 1991–2020, chosen as the nearest location with a full temperature record.
- Other locations: precipitation and snowfall come from the nearest location that publishes all twelve months of them, as named above.
- Comparisons: every Canadian town and neighbourhood of 2,500 or more, each read from its own nearest location; city totals and reserves are left out.
- 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.
