Weather in Berlin in December
Germany · 20-year averages, December
The month to avoid. December is the month most people should skip in Berlin. Highs sit at 3.1 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
December ranks 11 of 12 — near the bottom of Berlin's year. September is the month that works, and the swing between the two is 61 points, which is a different holiday rather than a slightly better one.
Rain on 12 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 3.1 °C the difference between a good day and a miserable one is entirely down to what you are wearing.
What the averages hide
Averages flatten a month, and this one hides a few things: 20 nights drop below freezing, so anything left outside stays frozen; the day barely swings — 4.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 13.5 °C and the coldest night fell to -19.1 °C.
December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 75 mm against 22 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 48 mm average is a reasonable planning figure, not a promise.
Wind is light at 12.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 94%, which at 3.1 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How December sits in the year
Temperatures hold steady either side: 7.6 °C in November, 3.1 here, 1.9 in January. Nothing about the timing within the month matters much.
Daylight in December
December sits at the dark end of Berlin's year — 7.7 hours of daylight against 16.8 at midsummer, losing 0.4 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
An inland climate
With no coast nearby, the year swings a fair way — 29 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
December in Berlin versus nearby
If Berlin is one option among several, the nearby comparison is worth making. Szczecin is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Liberec is close enough to be a coin toss — within a degree on temperature, 2 days more rain.
So: December is a compromise. September is 55 points better and is what Berlin is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
