Where Six Nations (Part) 40’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Hamilton from ECCC’s climate data site, the nearest location with every month of temperature.
- Other locations: ECCC blanks a month that fails its completeness rule, so the precipitation or snowfall here comes from the next location with all twelve months.
- 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.
