How Much Rain in May?

You can expect about 18 days this month with sunny, or at least partly sunny skies. 

Rainfall of 1 mm (0.04 inches) or more occurs on average, on 5 days during May.  


The number of daylight hours increases this month from about 14 hours on the 1st to nearly 15 hours by the 31st.


The wind in Barcelona this month tends to be mostly light to gentle at 6-19 kph/4-12 mph.

Ocean Temperatures

At the beach, ocean temperatures will warm gradually from about 16 C to 18 C (61-64 F) so swimming options will be limited to the more adventurous. 

What to Wear in Barcelona in May?

Spring attire will be best this month, however, there can be some warmer afternoons.

We recommend a light jacket or windbreaker, long-sleeved shirts, and tops, as well as some lighter attire for those few warmer afternoons.

Don’t forget some comfortable walking shoes! 

Things to Do in Barcelona in May

There will be a lot of sunny days in May, so this would probably be a good time to consider taking a pay-what-you-wish walking tour in Barcelona.

May will also be the month of Festival Ciutat Flamenco (Flamenco City), so there will be a lot of great opportunities to see Flamenco dancers performing at this time of year.

If you're looking for something fun to do after dark, May 15th will be the Night of the Museums, which means a lot of notable museums will be staying open late and there will also be music and dancing.

Looking for a concert to attend? Manolo García will be performing in Barcelona on May 18th, 2024.
