B.C. Winter Forecast

Back in September, The Weather Network predicted that British Columbia would have a milder winter, but that December was a “wild card.”

Since then, the winter forecast has been updated to include the most recent prediction, which calls for milder temperatures along the B.C. coast and across much of Northern B.C. While northeastern B.C. to the southern interior will see near normal temperatures.

While the north coast region is, “expected to see above average rainfall and alpine snow,” the south coast region is expected to be drier than normal. With this in mind, the forecast adds that this dry pattern may break at times during the season. During these breaks, the Lower Mainland could have the, “potential to see several weeks’ worth of precipitation in just 5 to 10 days.”
