Is the water clean at Embalse San Juan San Mart?n de Valdeiglesias?
Embalse San Juan San Mart?n de Valdeiglesias is a lake bathing site with an official EU Bathing Water rating of Excellent for the 2025 season — the highest official classification under the EU bathing-water assessment. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated 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. On site you'll find Beach bar, Restaurant, and Parking. You can park about ~140 m away.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect cooler, calmer water either side of that stretch. San Martín de Valdeiglesias — the closest town — sits about ~5.1 km from here.
That “Excellent” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. There are 2 places to eat within a kilometre — Bar Virgen de la Nueva is the closest, about ~200 m away.

Is the water warm at Embalse San Juan San Mart?n de Valdeiglesias today?

July–September tends to be the sweet spot for swimming here, with water temperatures usually peaking later in that stretch. That applies to the water around Ávila.
What's behind the water quality rating shown above?
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.
