Where La Sarre’s numbers come from
Averages over 30 years, not a forecast.
- Normals: the 1991–2020 normals from ECCC for Rouyn, its nearest location with complete temperatures.
- 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 towns and neighbourhoods of 2,500+ across Canada, each on its nearest normals location, without the city totals or the reserves.
- Not on this page: snowfall (no location within 100 km publishes a full year of it), sunshine (none for 1991–2020) and an altitude correction.
