Is the water clean at Jaz?
Jaz 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. On site you'll find Showers, Toilets, and Beach bar. There's parking about ~170 m from the beach.
That rating has been consistent: every one of the 5 classified seasons on record has come back Excellent or Good. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter.
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 4 places to eat within a kilometre — Plavi Jadran 2 is the closest, about ~110 m away.

How is bathing water quality actually assessed?
Behind the annual grade: a season of testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive. A few countries, Croatia via IZOR included, also publish individual in-season samples ahead of that report, but Jaz doesn't have one published yet.
