Polar vortex split may bring cold snap to Germany in early November
Polar vortex winds are slowing over the North Pole and may push freezing weather south to Germany in early November. Here’s what forecasters are predicting.
A recent split in the polar vortex could bring cold weather to Germany in early November. Meteorologists are predicting that the polar vortex winds, which typically slow down around January, have already started to weaken. On October 31, the wind speeds were recorded at 12.03 meters per second, equivalent to 43.2 km/h. By November 1 and 3, these speeds are expected to drop to 32.9 km/h and 14.9 km/h, respectively.
The polar vortex is crucial as it keeps the extremely cold winds over the North Pole. However, when it weakens, freezing temperatures can be pushed south towards Europe and North America. This scenario can be further exacerbated by a sudden stratospheric warming (SSW) over the North Pole, which can stretch and split the polar vortex, allowing cold air to descend to lower levels.
The forecast of a weakened polar vortex and SSW over the North Pole could bring a cold snap to Germany around November 4. This is unusual as it's the earliest such event since records began in the 1950s. The last occurrences of such a phenomenon happened in 1968 and 2025, but they began later in November.
While a weak polar vortex split is forecasted, it is expected to subside by November 11, meaning temperatures would rise again shortly after. However, this early forecast for a polar vortex split is noteworthy, given its unusual timing in the winter season.
