Berlin weather in December

December in Berlin is cold and grey, with average highs of 5.5°C (42°F) and lows of 1.2°C (34°F). You'll experience around 51mm of precipitation spread across roughly 13 rainy days, so expect frequent drizzle and occasional snow. Sunshine is scarce at just 2.6 hours per day, creating that classic winter atmosphere with long, dark afternoons.

This is peak Christmas market season in Berlin. The city transforms with festive decorations, holiday lights, and traditional wooden stalls selling mulled wine, roasted chestnuts, and handmade crafts. Crowds increase significantly in December, especially around the Weihnachtsmärkte at Alexanderplatz and the Brandenburg Gate. The cultural calendar fills with seasonal concerts, ballet performances, and New Year celebrations.

December 2026 is ideal if you love Christmas markets and don't mind cold, wet weather. Pack warm layers and waterproof gear—you'll need them. Accommodation and flights tend to be pricier than autumn months, but fewer tourists visit on rainy weekdays. If you prefer mild weather and smaller crowds, consider visiting Berlin in September or October instead.
