Barcelona weather reviews
Anna,
May 2023
Last year I attended the May holidays in Barcelona. The weather was wonderful all days. Sunny, partly cloudy during the day, which did not interfere with walks at all, air temperature up to 22 degrees. It was gloomy and cloudy for several days, but it never rained. Very comfortable weather for walking around the city and visiting attractions. There was practically no nighttime temperature difference: minimum 18 degrees.
