What kind of beach is this?
This beach belongs to a small coastal village. It's usually calmer than a resort or town beach, though a popular village spot can still fill up on the best summer days.

Is the water clean at Spiaggia Delle Sirene?
Spiaggia Delle Sirene 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 ~1.4 km away.
Over the 11 classified seasons on record, 10 have come back Excellent or Good — a track record worth checking each year rather than assuming. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. Nocelle — the closest town — sits about ~800 m 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 8 straight years. There are 2 places to eat within a kilometre — Ristorante Da Adolfo Di Bella Sergio is the closest, about ~50 m away.
Frequently asked questions
Can you safely swim at Spiaggia Delle Sirene?
It's about as safe as bathing water gets: Spiaggia Delle Sirene's 2025 EU rating is Excellent, the top tier on the scale, and 10 of 11 classified seasons have come back Excellent or Good. It's also held steady at Excellent for 8 straight years.
Is the sea warm at Spiaggia Delle Sirene today?
That reading, around 27°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.
What's the ideal time of year to swim at Spiaggia Delle Sirene?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch.
What does the water quality rating actually measure?
The grade comes from a full season of official sampling for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive, which assigns Excellent, Good, Sufficient or Poor. Some countries (Croatia, via IZOR) also publish individual in-season samples ahead of that report; Spiaggia Delle Sirene doesn't have that feed yet.
How do you get to Spiaggia Delle Sirene?
By car, there's parking about ~1.4 km from the beach. There's a bus stop about ~180 m from the beach. The nearest town is Nocelle, about ~800 m away.
