What to Wear in Barcelona during 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 during 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.
