Is the water clean at Gran Baia?
Gran Baia sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Good 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, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. There's parking about ~260 m from the beach.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. It's been a consistently reliable spot too — the rating has held at Good for 7 straight years. The nearest town, Avigliana, is about ~1.3 km away.
That “Good” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. There are 3 places to eat within a kilometre — Centro Velico Avigliana is the closest, about ~720 m away.
Frequently asked questions
Is Gran Baia safe to swim in?
Yes — Gran Baia's 2025 rating is Good, one step below the top tier, with 11 of 11 classified seasons rated Excellent or Good. It's also held steady at Good for 7 straight years.
What temperature is the sea at Gran Baia right now?
For Gran Baia, the ~23°C figure above is a stand-in value, not a live reading — the marine-weather feed was unreachable when the page last built, and it'll swap in automatically once the feed responds again. On the modeled climatology here, August usually runs warmest.
When is the best time to swim at Gran Baia?
If you're planning around water temperature, July–September is the window to target — the modeled sea temperature is typically highest then. Within that window, August is typically the single warmest month.
Who measures the water quality rating, and how?
It's based on official water samples: authorities test for intestinal enterococci and E. coli through the season, then report the full-season results to the European Environment Agency each spring, which assigns one of four grades — Excellent, Good, Sufficient or Poor. A few national authorities, including Croatia's IZOR, also publish individual samples during the season itself, ahead of that annual report — that isn't yet available for Gran Baia.
What's nearby Gran Baia — parking, buses, or a ferry?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Avigliana (Via Sant'Agostino 4), about ~1.5 km away. The nearest town is Avigliana, about ~1.3 km away.
