Where Douglas’s numbers come from
Averages over 30 years, not a forecast.
- Normals: 1991–2020 normals for Fredericton (Airport) from ECCC’s climate data site, the nearest location with every month of temperature.
- Comparisons: every place of 2,500+ in Canada but the city hubs and the reserves, each on its nearest ECCC location.
- 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.
