Is the water clean at Alonaki?
Alonaki 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 Epirus.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. The nearest town, Βαλανιδόραχη, is about ~2.1 km away.
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.

When should you plan a swimming trip to Alonaki?
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 Epirus. Within that window, August is typically the single warmest month.
Where does the water quality rating come from?
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 — Alonaki doesn't have that feed set up yet.
What's the easiest way to reach Alonaki?
There's no parking mapped within 1.5 km of Alonaki, so plan on a walk, or arrive early once it gets busy. The nearest town is Βαλανιδόραχη, about ~2.1 km away.
