Frequently asked questions
How warm is the water at Jarun, Veliko jezero right now?
That reading (~28°C) is a stand-in value rather than a live measurement — Jarun, Veliko jezero's marine feed was temporarily unreachable, and it'll refresh automatically once the feed returns. That's the reading right off Zagreb, City of Zagreb.
Which month has the warmest water at Jarun, Veliko jezero?
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 Zagreb, City of Zagreb.
Is the water temperature chart above measured or estimated?
Not currently for Jarun, Veliko jezero — 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 water temperature taken at each official water sample, and that's plotted alongside the modeled curve when it exists.
