Where Fergus’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Elora, 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: 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 (no 1991–2020 normals exist for it) and any altitude adjustment, since there is no elevation for the town itself.
