Frequently asked questions
What temperature is the sea at Migennes right now?
Treat the ~28°C above as illustrative only: the live marine feed for Migennes was unreachable when this page was built, and the figure updates automatically once it's back. That's the reading right off Yonne.
When is the best time to swim at Migennes?
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 Yonne.
Is the sea temperature chart above measured or estimated?
Not yet for Migennes — 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.
