Where Riverdale East’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Burlington Piers, 1991–2020, chosen as the nearest location with a full temperature record.
- 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: Canadian towns and neighbourhoods of at least 2,500, each placed by its nearest location (city totals and reserves excluded).
- 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.
