Common questions about swimming in Spain

Is it safe to swim in Spain?
Mostly yes. 87% of Spain's 2,296 officially monitored bathing sites hold the top "Excellent" class in the 2025 assessment, but 48 sites are rated Poor — bathing there is advised against or banned all season.
Which beaches in Spain should I avoid?
The 48 rated Poor: Arroyo Cimorro Navalacruz, Garganta Rio Tajo Valdecaas de Tajo, Laguna la Tomilla Ossa de Montiel, Laguna Villafranca Villafranca de los Caballeros 03, Laguna Villafranca Villafranca de los Caballeros 04, Playa Cala Egos and 42 more. Poor means the site failed the minimum standard across four seasons of sampling.
Where is the water cleanest in Spain?
1,819 sites have held the top rating five seasons running — a far better signal than a single good year. Around Malaga, Tarragona, Alicante you will find the densest clusters.
How often is water quality tested in Spain?
Through the whole bathing season. National sanitary authorities sample each official site for E. coli and intestinal enterococci, report to the European Environment Agency, and the published class reflects the last four seasons combined.

Ratings are the official season-long classification, computed from the last four seasons of sampling — not a live reading. After a storm any site can be temporarily worse; local advisories win.
