Barcelona in October
Around 18 °C by day, sea 21.9 °C. Warm enough to swim. Quieter than the peak: 3 of 4.
October in Barcelona is 18 °C by day and 21.9 °C in the sea. Technically you can still swim; in practice the city beaches are already chilly. The city itself, though, is at its easiest this month: the heat has gone and the summer crowd with it.
For anyone moving, October in Barcelona is the rain test. Autumn is the wettest season here; our base counts 56 rainy days a year, and it comes down hard and briefly. The city is built for it, but the streets by the sea in Barceloneta flood faster than those up in Gràcia, and that is worth seeing before you sign a lease. The square metre here costs €4,675 on the ministry's appraisal — on the whole mainland only San Sebastián at €5,107 and neighbouring Sitges at €4,829 are dearer.
