Winter 2025-26 Is Coming for Real: How La Niña, an Uneasy Polar Vortex and Early Cold Blasts Are Rewriting the Forecast for the U.S., Canada and Europe We’re headed into the winter of 2025-26 with more than just the usual seasonal transitions. A trio of powerful drivers—La Niña, a weakening Polar Vortex and early arctic cold outbreaks—are aligning to rewrite the playbook. Across North America and Europe, the 2025/26 winter season is shaping up to be one of contrasts and surprises. Winter 2025-26 Is Coming A Season in Flux: Why Winter 2025-26 Won’t Follow the Usual Script We’re headed into the winter of 2025-26 with more than just the usual seasonal transitions. A trio of powerful drivers—La Niña, a weakening Polar Vortex and early arctic cold outbreaks—are aligning to rewrite the playbook. Across North America and Europe, the 2025/26 winter season is shaping up to be one of contrasts and surprises. Here’s why this winter demands attention: Weak La Niña conditions are already in place and expected to persist, steering jet streams and storm tracks. The Polar Vortex is showing signs of early instability, raising the odds for major cold releases later this winter. North America has already recorded one of its earliest and most intense cold‐air surges in mid-November. Meanwhile Europe is locked into a wetter, stormier prelude to winter—not the instant freeze usually expected. These factors set the stage for a winter that might start warm and soggy in places, turn sharply colder in others, and evolve in unexpected ways.
