Is the water clean at Gradsko kupalište Petrinja?
Gradsko kupalište Petrinja is a river 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. There's parking about ~270 m from the beach.
Looking to avoid the busiest weeks? The water is typically warmest around August, with the most reliable swimming window running July–September; outside that stretch you'll find a cooler sea but a quieter beach. That rating has been consistent: every one of the 5 classified seasons on record has come back Excellent or Good. The nearest town, Petrinja, is about ~600 m away.
Worth remembering: “Not classified” isn't a live reading, it's an annual grade — Excellent, Good, Sufficient or Poor — set once a year from that season's water samples and describing the average, not this afternoon's conditions. For what the sea is doing right now, check the “Right now” panel and 7-day outlook above. It sits in Sisak-Moslavina. There are 10 places to eat within a kilometre — Štuka is the closest, about ~260 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 Gradsko kupalište Petrinja doesn't have one published yet.
