How warm are heated hotel pools in Barcelona?

Most heated hotel pools in the city are held somewhere between 26 and 29°C. Rooftop pools sit at the lower end because wind cools the surface; indoor and spa pools sit at the upper end.

Are heated pools open in winter in Barcelona?

Some are. Heating and winter opening are separate decisions: a number of rooftop pools are heated during the shoulder season but still close from November to March. The hotels marked open year-round in our database are the ones to look at for a winter swim.

Can non-guests use these pools?

A few sell day passes, most do not. Access rules change season to season, so treat any day-pass claim you read online as provisional and confirm with the hotel directly.

Barcelona hotels with heated pools

Barcelona's pool season is shorter than the weather suggests. These are the hotels where heating keeps the water swimmable when the air is not.

7 hotels in our database · Updated 19 Aug 2026

An unheated rooftop pool in Barcelona is a mid-June to mid-September proposition. Heating shifts that: April, May and October become realistic swimming months, and a handful of properties keep the water at temperature all year.

Every hotel below has heating confirmed on the property's own pool or wellness page, or by at least two independent sources. Where we could not confirm it, the hotel is marked research pending and its facts are not presented as fact.

Heating is not the same as year-round opening. Several rooftop pools here are heated but still close for winter maintenance — check the season note on each hotel page before booking a trip outside the summer months.
