Is the water clean at Gregolimano?
Gregolimano 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 Beach bar.
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, Λουτρά Γιάλτρων, is about ~4.0 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. It sits in Central Greece.
Frequently asked questions
Should you swim at Gregolimano?
Gregolimano is rated Excellent for 2025 — the top EU Bathing Water classification — with 11 of 11 classified seasons rating Excellent or Good, so yes. It's also held steady at Excellent for 11 straight years.
What is the sea temperature at Gregolimano today?
The figure above (about 23°C) is placeholder data — the live marine-weather feed wasn't reachable when this page was built, and the real reading will appear automatically once it is. That's the reading right off Central Greece. On the modeled climatology here, August usually runs warmest.
When should you plan a swimming trip to Gregolimano?
For swimming, July–September is usually the best call — that's the modeled window when the sea here runs warmest. That applies to the water around Central Greece. Within that window, August is typically the single warmest month.
Who measures the water quality rating, and how?
Once a year, national authorities report a full season of testing for intestinal enterococci and E. coli to the European Environment Agency, which grades the season Excellent, Good, Sufficient or Poor under the EU Bathing Water Directive. A handful of countries, including Croatia via IZOR, also publish individual in-season samples ahead of that report — Gregolimano doesn't have that feed set up yet.
What's the easiest way to reach Gregolimano?
There's no parking mapped within 1.5 km of Gregolimano, so plan on a walk, or arrive early once it gets busy. The nearest town is Λουτρά Γιάλτρων, about ~4.0 km away.
