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 Agios Petros?
Agios Petros 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. It sits in South Aegean. You can park about ~80 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 a cooler, calmer sea either side of that stretch. Κάτω Άγιος Πέτρος — the closest town — sits about ~500 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 11 straight years. There are 3 places to eat within a kilometre — Αψε Ψήσε is the closest, about ~420 m away.
Frequently asked questions
Is the water at Agios Petros safe right now?
It's about as safe as bathing water gets: Agios Petros's 2025 EU rating is Excellent, the top tier on the scale, and 11 of 11 classified seasons have come back Excellent or Good. It's also held steady at Excellent for 11 straight years.
Is the sea warm at Agios Petros 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. That's the reading right off South Aegean.
What's the ideal time of year to swim at Agios Petros?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around South Aegean.
What does the water quality rating actually measure?
National authorities sample the water for intestinal enterococci and E. coli bacteria through the bathing season and report the full-season results to the European Environment Agency each spring for the season just finished, which assigns one of four annual classifications — Excellent, Good, Sufficient or Poor — under the EU Bathing Water Directive. Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
Can you drive to Agios Petros?
By car, it's easy — parking is right by the beach. By ferry, the nearest landing is Gavrio, about ~1.7 km away. The nearest town is Κάτω Άγιος Πέτρος, about ~500 m away.
