Is the water clean at Oštro?
Thinking of swimming at Oštro? The short answer: its official EU Bathing Water rating for 2025 is Excellent — the highest official classification under the EU bathing-water 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, IZOR (Croatia's Institute of Oceanography and Fisheries) — publish individual water sample results during the season itself, ahead of the annual report. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. You can park about ~310 m away.
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 11 classified seasons on record has come back Excellent or Good. On site you'll find Showers, Beach bar, and Restaurant.
“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 sea conditions, see the “Right now” and 7-day outlook panels above. There's 1 place to eat near the beach — Sambuca Beach Bar & Grill - U.O. Mina, about ~240 m away.
Frequently asked questions
Is Oštro a safe beach for swimming?
Generally, yes. Oštro's 2025 EU Bathing Water rating is Excellent — the highest tier — backed by 11 of 11 classified seasons rated Excellent or Good. It's also held steady at Excellent for 11 straight years.
How cold or warm is the water at Oštro today?
That reading, around 25°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Kraljevica, Primorje-Gorski Kotar.
What's the ideal time of year to swim at Oštro?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch. That applies to the water around Kraljevica, Primorje-Gorski Kotar.
What does the water quality rating actually measure?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Oštro isn't yet covered by that in-season feed.

By car, there's parking about ~310 m from the beach. By bus, the nearest stop is Okretište "Oštro", about ~330 m away. The nearest town is Kraljevica, about ~1.0 km away.
