Grota - Beach finder

Know before you go. Tap any beach to see if the sea is calm enough for a swim today — wind, waves, sea temperature and the best hours to dive in.

Most weather apps tell you the wind speed. Grota tells you what that wind actually does to your beach. By combining live marine and weather data with the shape of the coastline - the islands, capes and bays that block or funnel the wind — it estimates the real wave conditions at the exact spot you're standing and scores it from 0 to 100 for swimming.

WHAT YOU GET • Swimming score — a clear 0–100 rating with a plain-language summary for any beach • Shelter analysis — see how well islands, headlands and bays protect your beach from the open sea • Wind & waves — live wind speed and direction, plus estimated wave height at your spot • Sea temperature — current water temperature, so you know before you dip a toe • Best time to swim — the calmest hours of the day, highlighted • 12-hour and 7-day forecasts — plan today or plan the whole weekend • UV index & air temperature — know when the sun is at its strongest • Favorites — save the beaches you love and check their scores at a glance

HOW IT WORKS Drop a pin on any beach. Grota pulls live data from Open-Meteo's weather and marine models, maps the surrounding coastline from OpenStreetMap, and runs a wind-exposure analysis to estimate how rough or calm the water really is. Set a beach's orientation for an even sharper read.

TUNED FOR THE ADRIATIC Grota is built around the Croatian coast — it understands local winds like the bura and jugo, and how the islands and channels shape them. It works on any coastline, but this is where it shines.

PRIVATE BY DESIGN No account. No sign-up. No tracking. Grota doesn't collect personal information, and your saved beaches stay on your device. Your location is used only to find beaches near you, and only when you ask.
