Is the water clean at Pera Gialos?
Pera Gialos is a coastal bathing site with an official EU Bathing Water rating of Good for the 2025 season — meets the EU bathing-water standard in the latest annual 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 Pebble shore, Beach bar, and Restaurant. There's parking about ~130 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. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The nearest town, Αστυπάλαια, is about ~100 m away.
Worth remembering: “Good” 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. It sits in South Aegean. There are 35 places to eat within a kilometre — Καράβο is the closest, about ~30 m away.
Frequently asked questions
Is Pera Gialos safe to swim in?
Yes — Pera Gialos's 2025 rating is Good, one step below the top tier, with 11 of 11 classified seasons rated Excellent or Good. That said, the rating slipped from Excellent to Good in 2025, so it's worth checking for current local advisories too.
What's the current water temperature at Pera Gialos?
Pera Gialos's sea temperature currently sits at around 25°C, based on the latest update — check the “Right now” panel above for the full live picture. That's the reading right off South Aegean. On the modeled climatology here, August usually runs warmest.
When should you plan a swimming trip to Pera Gialos?
For the warmest water, aim for July–September — that's when the modeled sea temperature is typically at its best. That applies to the water around South Aegean. Within that window, August is typically the single warmest month.
Who measures the water quality rating, and how?
It's based on official water samples: authorities test for intestinal enterococci and E. coli through the season, then report the full-season results to the European Environment Agency each spring, which assigns one of four grades — Excellent, Good, Sufficient or Poor. A few national authorities, including Croatia's IZOR, also publish individual samples during the season itself, ahead of that annual report — that isn't yet available for Pera Gialos.
What's the easiest way to reach Pera Gialos?
By car, it's easy — parking is right by the beach. There's a bus stop about ~40 m from the beach. By ferry, the nearest landing is Αστυπάλαια-Λιμάνι Πέρα Γυαλού, about ~270 m away. The nearest town is Αστυπάλαια, about ~100 m away.
