Hardly any Canadian towns wake to less frost than Deer Lake
Sunny July days climb to about 23.0°C. A year here swings 20°C from midwinter lows to midsummer highs. By precipitation alone, it ranks wetter than 97% of Canadian towns. The furnace earns its keep from November to March, the months that average under 10°C.
Borrowed figures: Deer Lake has no normals station, so these come from Vancouver (Harbour), 11 km north-west.

Where Deer Lake’s numbers come from
Averages over 30 years, not a forecast.
- Normals: Environment and Climate Change Canada’s 1991–2020 normals, Vancouver (Harbour): the nearest of its locations with every month’s temperatures.
- Other locations: where a location publishes no full year of precipitation or snowfall, the nearest one that does supplies it, named beside those figures.
- Comparisons: every Canadian town and neighbourhood of 2,500 or more, each read from its own nearest location; city totals and reserves are left out.
- Not on this page: sunshine (no 1991–2020 normals exist for it) and any altitude adjustment, since there is no elevation for the town itself.
