Is the water clean at Lac Departemental de Blasimon?
Lac Departemental de Blasimon sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Excellent for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. It sits in Gironde. You can park about ~240 m away.
Looking to avoid the busiest weeks? The water is typically warmest around August, with the most reliable swimming window running July–September; outside that stretch you'll find a cooler sea but a quieter beach. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. On site you'll find Toilets, Kids' area, and Parking. Blasimon — the closest town — sits about ~1.1 km from here.
“Excellent” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above.
Frequently asked questions
Can you safely swim at Lac Departemental de Blasimon?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 11 of the 11 classified seasons on record have rated Excellent or Good. It's also held steady at Excellent for 2 straight years.
How cold or warm is the water at Lac Departemental de Blasimon today?
That reading, around 24°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Gironde.
What's the best month to visit Lac Departemental de Blasimon for swimming?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Gironde.
How is the water quality rating measured?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Lac Departemental de Blasimon isn't yet covered by that in-season feed.

By car, it's easy — parking is right by the beach. By bus, the nearest stop is Blasimon Bourg, about ~1.0 km away. The nearest town is Blasimon, about ~1.1 km away.
