Where Dawn-Euphemia’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Ridgetown 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: 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: a sunshine figure (ECCC published none for 1991–2020) and any lapse-rate correction for height, as the town has no elevation here.
