Frequently asked questions
What is the sea temperature at Poulithra today?
Treat the ~25°C above as illustrative only: the live marine feed for Poulithra was unreachable when this page was built, and the figure updates automatically once it's back. That's the reading right off Peloponnese.
When is the best time to swim at Poulithra?
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 Peloponnese.
Is the sea temperature chart above measured or estimated?
Not yet for Poulithra — 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.
