Late spring and early summer is the finest weather here. Entertain with the mild to warm temperatures and frequently sunny skies. By the end of June, the Mediterranean waters surrounding the city are warm enough for swimming. July and especially August can get disagreeably hot. Summer is an expensive time here because the schools are on vacation, and continuous droves of tourists pour into city. Majority of city’s festivals take place in the spring and summer. Europe’s biggest electronic festival takes place in June and Good Friday is one of largest citywide parties. Summer time is one of the best times to visit Barcelona with family and friends.
