Alberta’s fall outlook holds mild weather with chilly interruptions
Early snow and hard freezes aren’t out of the question across Alberta this autumn
Fall is a season of transition and Alberta often takes a front-row seat to the swinging pendulum of autumn weather.
The season ahead looks to buy some breathing room for folks throughout the province after a stormy summer left operations running behind.

Hiccups in the pattern are guaranteed during this season of change.
A patient, changeable autumn in store for Alberta
Warmer and drier weather should provide a longer runway for delayed harvest operations after the relentless storms and heavy rain Alberta experienced during the summer months.
El Niño will remain a significant driver of our autumn ahead, with mild Pacific air occasionally flowing across the Rockies.
While it’s unlikely that wintry weather will lock in early across the region, early tastes of winter are still possible. This is Alberta, after all, where the average first snowfall arrives around Sept. 27 in Calgary and Oct. 1 in Edmonton.
But repeated spells of mild weather should follow chilly interruptions expected to bring early winter-like weather, during which we may see periods of snow or hard freezes.
We’ll closely watch potential disruptions in the pattern, especially from typhoons recurving out of the western Pacific basin.
Frequently asked questions
Q: Does a warmer fall mean we’ll coast through and winter weather won’t arrive until December?
A: Hard no. Snow, hard freezes, and Arctic air are normal parts of the transition through fall. Our forecast is made to identify the dominant pattern, and cold spells are more likely to be interrupted by mild weather rather than becoming the permanent pattern.
Q: Will ski season be delayed?
A: We’re carefully watching central and eastern Canada, where there’s a real risk of delays, while western Canada looks more nuanced and will be elevation-dependent. Previous strong El Niños have even delivered above-average snowfall amounts to B.C.’s mountains.
Q: The fall forecast sounds kind of boring. Are we destined for a storm-free season?
A: No. Even if precipitation finishes below normal, the season can still produce a handful of memorable, major storms.
Q: Could Canada face a historic fall storm?
A: Yes. Fewer storms doesn’t mean weaker storms, and one major event can define how an entire season is remembered.
Q: Does El Niño mean a mild winter?
A: Keep an eye out for our Winter Sneak Peek release in the coming weeks. The winter forecast will depend on how El Niño evolves and several other atmospheric factors.
Q: Will we get an early snowstorm?
A: It depends where you reside. Victoria, B.C.: highly unlikely. Churchill, MB: count on it. All it takes is a sharp pattern disruption that would temporarily overwhelm the dominant pattern.
The most important question isn’t whether winter weather appears, but whether it sticks around.
Winter weather will knock at times. This year, don’t expect it to move in right away.
