Frequently asked questions
How cold or warm is the water at Larros today?
That reading (~25°C) is a stand-in value rather than a live measurement — Larros's marine feed was temporarily unreachable, and it'll refresh automatically once the feed returns. That's the reading right off Gironde.
What's the best month to visit Larros for swimming?
Aim for July–October — 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 Gironde.
Is the sea temperature chart above measured or estimated?
Not currently for Larros — 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.
