Every August, the Farmers’ Almanac releases its long-range Canadian winter forecast, and every April, the same question comes back around: how did it play out. This page recaps what we called for the 2025 to 2026 season, the climatology that shapes every Canadian winter (Alberta Clippers, lake-effect snow, the Pineapple Express), and how our long-range formula actually works.
The 2025-26 Call: A Classic Canadian Winter
On August 11, 2025, from our newsroom in Lewiston, ME, the Farmers’ Almanac released its 2025-26 Extended Winter Forecast for Canada. The headline: a return to a classic Canadian winter, with deep freezes, heavy snow, and powerful storms from coast to coast. That call was based on our time-tested prediction formula, refined over more than 200 years, factoring in sunspots, lunar cycles, tidal action, and planetary position.
Arctic air was expected to take a firm hold over the Prairie Provinces (Alberta, Saskatchewan, Manitoba), as well as northern Quebec and Labrador, for much of the season. Coldest stretches were pointed at January and February.
Whiplash Weather for the South and West
Southern Ontario, southern Quebec, and coastal British Columbia were called for more ups and downs: sharp cold snaps mixed with occasional thaws. Southern coastal BC was flagged for brief warming trends, especially in February and early March, arriving hand-in-hand with heavy rain and gusty winds off the Pacific. This is the whiplash pattern regular Canadian winters produce most years, and it is worth calling out separately from the deep-freeze zones.
Snow, Storms, and Soakers
If snow was your thing, there was plenty of it in the outlook. Per the Almanac’s long-range read, Eastern Newfoundland, Labrador, and Quebec were called for heavy snow, particularly in late January and February. Southern and eastern Ontario were flagged for frequent snowstorms and icy, lake-effect squalls, while the Prairies were braced for whiteouts driven by Alberta Clippers. Interior BC’s higher elevations were expected to see heavy snows whenever Pacific storms rolled through.
Rain was expected to feel relentless on the West Coast, but overall, we called for about average precipitation for British Columbia. Nova Scotia and Prince Edward Island were not left out: frequent rain-snow mixes and the threat of coastal flooding during strong systems.
The Climatology Behind a “Classic” Canadian Winter
When we say “classic Canadian winter,” we mean a season shaped by four repeatable patterns. These are the climatological features Environment and Climate Change Canada tracks year after year, and they are worth knowing before any forecast makes sense.
- Alberta Clippers: fast-moving low-pressure systems that spin off the Rockies, race east across the Prairies, and drop light but blowing snow. They arrive quickly, hit hard, and leave whiteout conditions in their wake.
- Lake-effect snow: when arctic air passes over the still-open Great Lakes, it picks up moisture and dumps it as heavy squalls on downwind shorelines. Southern and eastern Ontario see the sharpest bands.
- Pineapple Express: a warm, moisture-loaded plume from the subtropical Pacific that soaks coastal British Columbia. It brings the rain that makes BC winters feel relentless.
- Polar vortex intrusions: when the ring of cold air over the Arctic weakens, lobes of it slide south over the Prairies, northern Quebec, and Labrador. That is the deep-freeze mechanism behind the coldest weeks.
Environment and Climate Change Canada publishes daily and seasonal climate summaries once each season closes, and they are the authoritative record for what actually happened. See the government’s Canadian Climate Normals for the 1991 to 2020 baseline that “classic” is measured against.
Regional Breakdown: What Each Zone Was Told to Watch
How the Almanac’s 200-Year Formula Actually Works
Our long-range formula is not a black box, even if it stays private. It reads four cyclical inputs and matches the current pattern against a long historical library:
- Sunspot activity: the roughly 11-year solar cycle correlates with shifts in atmospheric circulation.
- Tidal action of the Moon: lunar gravitational pull nudges ocean and atmospheric behavior on measurable schedules.
- Position of the planets: orbital positions the formula treats as long-cycle reference points.
- Historical analog matching: the pattern for a given month is matched to closest historical analog months from more than 200 years of records.
The formula’s stated accuracy is about 80 percent, and we say that plainly. It is a long-range outlook, not a next-week forecast. Short-range models from Environment and Climate Change Canada or your provincial weather service beat any long-range formula for the next 7 to 10 days, and they should be your first stop when a storm is coming.
A Winter to Remember
The 2025 to 2026 winter forecast called for dramatic contrasts and plenty of memorable moments, whether shoveling out in Ontario, braving blizzards on the Prairies, or dodging rainstorms in BC. Canadians were told to stay bundled up and weather-aware, and the country was framed to face a true classic winter. Whether every zone landed exactly on that call is what the seasonal climate summaries from Environment and Climate Change Canada eventually settle.

Plan for the Next Canadian Winter
The season closes, then the next one starts building. If you want a head start on the coming Canadian winter, three practical steps go a long way:
- Check the current Canadian Extended Forecast for the seven regional zones we track.
- Compare it against the 30-year climate normals for your city so you know what “normal” actually looks like where you live.
- Sign up for local weather alerts through Environment and Climate Change Canada or your provincial service so short-range storm warnings reach your phone.
Canadian Winter Forecast FAQ
What did the Farmers’ Almanac Canadian winter forecast predict for 2025-26?
Released August 11, 2025, the outlook called for a classic Canadian winter, with deep freezes over the Prairies, northern Quebec, and Labrador, heavy snow across Eastern Newfoundland, Labrador, Quebec, and southern and eastern Ontario, and about average precipitation for British Columbia with a wet, blustery West Coast pattern.
How accurate is the Farmers’ Almanac Canadian winter forecast?
Our long-range formula is stated at about 80 percent accuracy. It performs best on broad seasonal patterns (colder or warmer than average, wetter or drier) rather than on the timing of any single storm. For the next 7 to 10 days, short-range models from Environment and Climate Change Canada will always beat any long-range outlook.
What is an Alberta Clipper?
An Alberta Clipper is a fast-moving low-pressure system that forms in the lee of the Rocky Mountains in Alberta and races east across the Prairies. Clippers move quickly and carry limited moisture, but they arrive with sharp temperature drops, strong winds, and blowing snow that produces whiteout conditions.
Why does southern Ontario get lake-effect snow?
When cold arctic air passes over the still-unfrozen surfaces of Lakes Huron, Erie, and Ontario, it picks up moisture and heat. That air then dumps the moisture as intense, narrow bands of snow on downwind shorelines. Southern and eastern Ontario sit directly in the classic downwind zones.
Why does coastal British Columbia get more rain than snow in winter?
The Pacific Ocean keeps coastal BC mild, and the Pineapple Express carries warm, moisture-loaded air from the subtropical Pacific onto the coast. That combination produces heavy rain rather than snow at low elevations, while the same storms drop heavy snow on the Rockies and interior mountains above about 1,000 metres.
How does the Farmers’ Almanac Canadian winter forecast get made?
The forecast uses a 200-plus-year formula that reads sunspot activity, the tidal action of the Moon, the position of the planets, and matches the current cyclical pattern against a long historical library of analog winters. The formula is refined but not published, and it has been in use since 1818.
Where can I find the official Canadian seasonal climate summary?
Environment and Climate Change Canada publishes national and regional climate summaries at the end of each season through the Canadian Climate Normals and the National Climate Data and Information Archive. That is the authoritative record for what actually happened, temperature-wise and precipitation-wise, at more than 8,000 monitoring sites across the country.
