Weather in Zaragoza in December

A good month. December works. It is not the peak, but nothing about it fights you. Highs sit at 13.2 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

December ranks 8 of 12 in Zaragoza: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Layers, and a genuinely waterproof outer — at 13.2 °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: 4 nights fall below freezing. Across the twenty years measured, the hottest December day reached 21.1 °C and the coldest night fell to -5.3 °C.

December is moderately variable: 1 mm in the driest year against 43 mm in the wettest, around an average of 19 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 11.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, which at 13.2 °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: 16.7 °C in November, 13.2 here, 12.9 in January. Nothing about the timing within the month matters much.

Daylight in December

December sits at the dark end of Zaragoza's year — 9.2 hours of daylight against 15.2 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 — 31.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

December in Zaragoza versus nearby

If Zaragoza is one option among several, the nearby comparison is worth making. Gasteiz / Vitoria is the weaker option in December — 3.5 °C cooler, 9 days more rain. Valencia is a better bet in December — 3.7 °C warmer, the same number of rain days.

So: December works, with October the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
