Is the water clean at Otok Sv. Nikola - Plaža Oliva?
Otok Sv. Nikola - Plaža Oliva sits on a stretch of coast classed as a coastal bathing site, carrying an official EU Bathing Water rating of Excellent for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow 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. It sits in Poreč, Istria.
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 cooler water but a quieter beach. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. On site you'll find Lifeguard, Showers, and Toilets.
“Excellent” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day water conditions, see the “Right now” and 7-day outlook panels above. There's 1 place to eat near the beach — Oliva Grill, about ~120 m away.
