Is the water clean at Megali Ammos?
Thinking of swimming at Megali Ammos? The short answer: its official EU Bathing Water rating for 2025 is Excellent — the highest official classification under the EU bathing-water assessment. That rating is set once a year under the EU Bathing Water Directive, from a full season of testing for intestinal enterococci and E. coli reported to the European Environment Agency the following spring, so the 2025 season's grade appeared in spring 2026 and the 2026 season won't be graded 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.
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 1 classified seasons on record has come back Excellent or Good. On site you'll find Sandy shore and Beach bar. The nearest town, Μηνιά, is about ~1.0 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. There's 1 place to eat near the beach — Tortuga Beach Bar, about ~60 m away.
