Where Matagami’s numbers come from
Averages over 30 years, not a forecast.
- Normals: ECCC’s normals for Matagami, 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: 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: snow, with no complete snowfall normals within 100 km, sunshine, which ECCC published for no location, and any height adjustment.
