Fall temperature outlook
Meteorological fall started on September 1, and the astronomical fall will be upon us on September 22.
Each season has both a meteorological start and an astronomical start. It sounds complicated, but it’s not! The meteorological fall is simply a date meteorologists have picked for statistical reason, and it is based on the 12-month calendar and the annual temperature cycle. On the other hand, the astronomical fall is based on the position of the Sun in relation to the Earth.
Since fall has already started for us, here is our seasonal outlook:
Warmer than normal temperatures have dominated across most of Canada during the first week of September, and we expect it to continue well into meteorological fall.
Above average temperatures are expected for most of eastern Canada, particularly over the Great Lakes, southern Quebec, the Maritimes and Newfoundland. Warm conditions are also expected to persist across the Prairies and the Arctic. The possible cooling effects of the ongoing La Niña event still bring some uncertainty over Western Canada. The event’s magnitude is expected to be small, but it could strengthen before returning to a neutral trend over the winter.
We also expect more hurricanes to form throughout the fall, following a record-breaking quiet month of August with no named storms. September is usually the peak of the hurricane season, and combined with a warmer than normal ocean water temperatures in the eastern Atlantic, the risk of tropical activity in the region is high.
