Is the water clean at Foce Sisto?
Foce Sisto is a coastal 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 Sandy shore and Toilets. There's parking about ~440 m from the beach.
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. Over the 11 classified seasons on record, 10 have come back Excellent or Good — a track record worth checking each year rather than assuming. The nearest town, San Felice Circeo, is about ~6.2 km away.
Worth remembering: “Excellent” isn't a live reading, it's an annual grade — Excellent, Good, Sufficient or Poor — set once a year from that season's water samples and describing the average, not this afternoon's conditions. For what the sea is doing right now, check the “Right now” panel and 7-day outlook above. There are 2 places to eat within a kilometre — Bar Ezio Fashion Cafè is the closest, about ~650 m away.
