Where Vellore’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Toronto Buttonville (Airport), 1991–2020, chosen as the nearest location with a full temperature record.
- Comparisons: a pool of Canadian towns and neighbourhoods of 2,500 or more, read alike; whole cities and reserves stay out of it.
- 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.
