Where Notre-Dame-des-Prairies’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for L'Assomption, 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: all Canadian places of 2,500 or more except city totals and reserves, each read the same way.
- 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.
