Where Saint-Siméon’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for New Carlisle from ECCC’s climate data site, the nearest location with every month of temperature.
- Other locations: precipitation and snowfall come from the nearest location that publishes all twelve months of them, as named above.
- 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, which none of ECCC’s 450 locations publishes for 1991–2020, and the town’s own height above sea level, so no figure is adjusted for altitude.
