Barcelona, like any other Spanish city, is worth visiting at any time of the year, but during the summer months, the city is indeed very crowded with tourists. We recommend renting your RV or camper van in Barcelona for some time between May and June, as the temperatures start to rise, the tourist crowds are still ok, and there are several events in the city.
Summer in Barcelona is anything but calm and relaxed. There are tourists from all over the world, high temperatures accompanied by crowded beaches, and the prices of everything tend to rise due to the high season.
During autumn and winter, it’s very likely to rain, but being a city located directly on the Mediterranean, temperatures remain stable. Plus, there are fewer tourists during this time.
