What is the weather like in Barcelona in December?
December in Barcelona is mild by UK standards, but it feels distinctly wintery, especially in the evenings. Daytime highs typically hover between 13°C and 15°C (mid-50s °F), dropping to 7–9°C at night. While the live forecast above shows the immediate outlook, the month averages around 40mm of rain spread over 8–10 days, so showers are possible but not constant. Sunshine is limited to about 4–5 hours per day, so plan indoor activities for late afternoons.
Should I visit Barcelona in December?
Yes, if you prefer fewer crowds and lower accommodation prices. The Christmas markets and festive lights along Las Ramblas are a highlight, and the mild climate means you can still enjoy outdoor sightseeing without the summer heat. Pack layers, a waterproof jacket, and comfortable walking shoes. For a broader perspective on Spain, check Marrakech Weather for a warmer alternative, or compare with Paris Weather for a chillier city break.
