Is the water clean at De Castelan?
De Castelan is a coastal bathing site with an official EU Bathing Water rating of Not classified for the 2025 season — not enough samples in this year to assign an official rating. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, IZOR (Croatia's Institute of Oceanography and Fisheries) — publish individual water sample results during the season itself, ahead of the annual report. You can park about ~150 m away.
De Castelan does not yet have enough classified seasons to describe a long-run trend. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect cooler, calmer water either side of that stretch.
That “Not classified” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. There are 5 places to eat within a kilometre — Beach Bar De Castelan is the closest, about ~50 m away.
