Frequently asked questions
How warm is the sea at Ledano right now?
Ledano's sea temperature is currently around 19°C, based on the most recent hourly reading. See the 7-day chart above for the short-term trend and the monthly chart further down for the seasonal typical. That's the reading right off Côtes-d'Armor.
What's the ideal time of year to swim at Ledano?
Aim for July–September — the modeled water temperature typically clears 22°C in that window, the rule of thumb for comfortably warm swimming, with August usually the peak. That applies to the water around Côtes-d'Armor.
Is the sea temperature chart above measured or estimated?
Not currently for Ledano — the chart above is a modeled estimate based on latitude and season rather than a measured average. A few countries (Croatia, via IZOR) do publish the sea temperature taken at each official water sample, and that's plotted alongside the modeled curve when it exists.
