Frequently asked questions

How warm is the sea at Playa O Porti?o do Maio right now?

That reading (~25°C) is a stand-in value rather than a live measurement — Playa O Porti?o do Maio's marine feed was temporarily unreachable, and it'll refresh automatically once the feed returns. That's the reading right off A Coruña.

What's the ideal time of year to swim at Playa O Porti?o do Maio?

Aim for June–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 A Coruña.

Is the sea temperature chart above measured or estimated?

Not currently for Playa O Porti?o do Maio — 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.
