Winter forecasts for Germany vary between historical calendars and DWD outlooks

Meteorologists and historical calendars are providing differing outlooks for the upcoming winter season in Germany, specifically regarding regions like Baden-Württemberg. A 100-year calendar predicts a cold, snowy December for 2026, characterized by a 'Mercury year' with significant frost. However, the German Weather Service (DWD) notes that such calendars are based on traditional folk rules rather than systematic long-term data and cannot account for specific regional or altitude variations.

In contrast, the DWD indicates a tendency toward a milder winter in southern Germany. This outlook is influenced by the El Niño phenomenon in the Pacific, which typically increases the probability of milder temperatures during the early winter months of November and December in Western Europe.
