Is the water clean at Collettore Di Cuma?
Thinking of swimming at Collettore Di Cuma? The short answer: its official EU Bathing Water rating for 2025 is Good — meets the EU bathing-water standard in the latest annual assessment. That rating is set once a year under the EU Bathing Water Directive, from a full season of testing for intestinal enterococci and E. coli reported to the European Environment Agency the following spring, so the 2025 season's grade appeared in spring 2026 and the 2026 season won't be graded until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. Water quality here has been improving: the rating moved from Sufficient to Good in 2025. There's parking about ~780 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. Over the 11 classified seasons on record, 3 have come back Excellent or Good — a track record worth checking each year rather than assuming. The nearest town, Cuma, is about ~1.3 km away.
Worth remembering: “Good” 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.
