Is the water clean at Zona Ant. Piazza Sirena?
Zona Ant. Piazza Sirena sits on a stretch of coast classed as a coastal 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. You can park about ~210 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, Beach bar, and Restaurant. Francavilla al Mare — the closest town — sits about ~500 m 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. There are 23 places to eat within a kilometre — Trieste Pizza is the closest, about ~70 m away.
