Frequently asked questions
What's the current water temperature at Eretria Anatolika?
Treat the ~23°C above as illustrative only: the live marine feed for Eretria Anatolika was unreachable when this page was built, and the figure updates automatically once it's back. That's the reading right off Central Greece.
When is the best time to swim at Eretria Anatolika?
June–October, when the modeled water temperature is typically above 22°C — widely considered comfortably warm for swimming. August usually runs warmest. That applies to the water around Central Greece.
Is the sea temperature chart above measured or estimated?
Not yet for Eretria Anatolika — the chart above shows a modeled estimate derived from latitude and season, not a measured average. Some countries (Croatia, via IZOR) also publish the sea temperature recorded at each official water sample; when that data exists for a beach it's plotted alongside the modeled curve.
