Barcelona – What you should know
Barcelona enjoys a mild Mediterranean climate with hot summers and pleasant winters. From June to September, temperatures typically reach 26–31°C (79–88°F) and the Mediterranean warms to 24–26°C (75–79°F) — perfect for a beach-and-city holiday. The bathing beaches of the Barceloneta are right in the city, ten minutes' walk from the old town.
Spring (April/May) and autumn (September/October) are the ideal travel months for cultural travellers: temperatures of 18–24°C (64–75°F), considerably fewer tourists than in high summer and the Eixample terraces still relaxed. July and August are high season — hot, crowded and expensive, but the sea and nightlife are at their annual peak.
