What kind of beach is this?
This beach belongs to a small coastal village. It's usually calmer than a resort or town beach, though a popular village spot can still fill up on the best summer days.
Estimated from OpenStreetMap surroundings data (ODbL).
Is the water clean at Lermot?
Thinking of swimming at Lermot? 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, the national environmental authority — 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 2 straight years. You can park about ~150 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. Over the 11 classified seasons on record, 8 have come back Excellent or Good — a track record worth checking each year rather than assuming. On site you'll find Toilets and Parking. Hillion — the closest town — sits about ~1.9 km from here.
“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 — Camping Bellevue Mer ***, about ~740 m away.

What's behind the water quality rating shown above?

Some national authorities, including Croatia's IZOR, also publish individual in-season sample results ahead of that annual report.
