Barcelona in May

One of the best months for city sightseeing. The sun is bright without being oppressive, which suits Park Güell and Montjuïc. The Primavera Sound music festival fills the Parc del Fòrum from late May into early June. The sea is still too cold for most swimmers.

May in Barcelona was on the warm side, averaging 22°C by day and 15°C at night. With about 5 rain days, showers were an occasional nuisance rather than the rule. Averages hide a lot here: one year saw 2, another 11.

Long days, up to 15.0 hours of light, left room for a late stroll after dinner. May 2022 averaged 24.7°C by day, 2.4°C above the 20-year mean.
