Barcelona in December
Around 10.5 °C by day, sea 15.6 °C. Too cold to swim. Quieter than the peak: 3 of 4.
December in Barcelona is 10.5 °C by day, sea at 15.6 °C. This is a working city in a working month: load 3 out of 4. Of the forty-odd Mediterranean places in our base only six hold a December load of 3, and all six are cities rather than resorts. The difference shows not in the weather but in what is open — here, everything is.
For someone moving, December is useful for one thing: it is the most honest month for light. The day is at its shortest, the sun goes early, and a flat with north-facing windows shows exactly what it is. With 2,500 hours of sunshine a year Barcelona is a bright city — but the yearly figure is spread unevenly, and a December weekend explains that better than any table. The square metre in the city is €4,675, a one-bedroom rents at €1,150 a month on the registry.
