What Gdańsk is like in December
December sits between a milder November (high 7.5°C, 11 rain days) and a colder, slightly wetter January (high 2.9°C, 13 rain days) — the temperature keeps dropping through the month while rain stays frequent. It's the 3rd wettest month by rain days and the least sunny of the year, so grey skies are the norm. Among nearby cities for the same month, Wrocław is both milder and drier (high 4.9°C, 11 rain days), while Warsaw (3.6°C, 12 rain days), Berlin (5.2°C, 12 rain days) and Copenhagen (5.5°C, 12 rain days) see about the same number of rain days as Gdańsk; only Malmö (5.4°C, 13 rain days) is wetter. Daylight shrinks steadily, from 7h39min on the 1st to the year's shortest day on the 21st (7h18min).
Christmas Eve, Christmas Day and St. Stephen's Day (24–26 December) fall in the month, and school holidays in Germany, the Netherlands and France overlap Christmas week, bringing family travellers into town even as the wider region stays quiet — visitor nights run at 0.5 times an average month, among the lowest of the year. It's a month for wandering the Long Market with mulled drinks in hand, ducking into museums and churches, and letting evenings run long since there's little daylight to lose. Outdoor plans work best bundled up and timed around midday.
