Weather in Kraków in December
Poland · 20-year averages, December
The month to avoid. Of the twelve, December is the one to avoid. Highs sit at 2.5 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
December ranks 10 of 12 — near the bottom of Kraków's year. September is the month that works, and the swing between the two is 58 points, which is a different holiday rather than a slightly better one.
Rain on 11 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 2.5 °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: 24 nights drop below freezing, so anything left outside stays frozen; the day barely swings — 5.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 14.6 °C and the coldest night fell to -20.2 °C.
December is moderately variable: 18 mm in the driest year against 97 mm in the wettest, around an average of 41 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.
Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 92%, which at 2.5 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How December sits in the year
The month is on the way down: 6.1 °C cooler than November, with January dropping another 1.8 °C. The first week and the last are not the same trip.
Daylight in December
December sits at the dark end of Kraków's year — 8.1 hours of daylight against 16.3 at midsummer, holding steady all 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 — 31.6 °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 Kraków versus nearby
If Kraków is one option among several, the nearby comparison is worth making. Wrocław is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Warsaw is close enough to be a coin toss — within a degree on temperature, 1 day less rain.
So: December is a compromise. September is 53 points better and is what Kraków is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
