In October, the St. Ursula folk rule is used to suggest whether Christmas will be snowy based on the weather on October 21st. The German Weather Service (DWD) notes that while these rules are based on long-term observations, there is no scientific evidence for such single-day predictions. In November, St. Martin’s Day traditions involve using weather patterns to predict the severity of the upcoming winter. Local proverbs suggest that frost or snow, described as “Martini has a white beard,” indicates a long, hard winter, while sunshine may signal a cold season. Conversely, fog or damp conditions are often interpreted as signs of a mild winter. The DWD provides meteorological updates for these periods, noting unsettled conditions and rain in various regions such as Bavaria and North Rhine-Westphalia. ## Timeline ### 2026-11-10: German folklore traditions and weather predictions for St. Martin's Day German folklore uses weather on St. Martin's Day to predict winter severity, with proverbs linking fog, sun, or snow to upcoming temperatures. 5 sources. https://clstr.news/cluster/german-folklore-traditions-and-weather-predictions-for-st-martins-day ### 2026-10-19: Germany weather: Folk rules and meteorological updates German weather discussions focus on St. Ursula folk rules predicting Christmas snow, while meteorologists urge caution.
