Frequently asked questions
Is the sea warm at Prapratno today?
That reading (~27°C) is a stand-in value rather than a live measurement — Prapratno's marine feed was temporarily unreachable, and it'll refresh automatically once the feed returns. That's the reading right off Ston, Dubrovnik-Neretva.
Which month has the warmest sea at Prapratno?
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 Ston, Dubrovnik-Neretva.
Is the sea temperature chart above measured or estimated?
Not currently for Prapratno — 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.
