Weather in Budapest in December
Hungary · 20-year averages, December
The month to avoid. Of the twelve, December is the one to avoid. Highs sit at 3.4 °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 Budapest's year. September is the month that works, and the swing between the two is 56 points, which is a different holiday rather than a slightly better one.
Rain on 9 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 3.4 °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: 22 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 16 °C and the coldest night fell to -17.2 °C, and the wettest single day dropped 30 mm — roughly 70% of the month's rain in one day.
December is moderately variable: 5 mm in the driest year against 91 mm in the wettest, around an average of 43 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.
Wind is light at 9.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 91%, which at 3.4 °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: 10 °C in November, 3.4 here, 2.5 in January. Nothing about the timing within the month matters much.
Daylight in December
December sits at the dark end of Budapest's year — 8.5 hours of daylight against 15.9 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 — 33.2 °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 Budapest versus nearby
If Budapest is one option among several, the nearby comparison is worth making. Szeged is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Debrecen is close enough to be a coin toss — within a degree on temperature, 1 day less rain.
So: December is a compromise. September is 54 points better and is what Budapest is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
