What kind of beach is this?

Is the water clean at Kalamia?
Kalamia 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 Ionian Islands. There's parking about ~140 m from the beach.
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. The nearest town, Τήνος, is about ~700 m away.
“Excellent” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above. There are 34 places to eat within a kilometre — Argy´s is the closest, about ~240 m away.

When should you plan a swimming trip to Kalamia?
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 Ionian Islands. 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 — Kalamia doesn't have that feed set up yet.
