About Fangass: Sargassum Forecast

Which beach is sargassum-free today? Fangass tells you every morning, beach by beach. WHAT'S INSIDE • A live map of 154 beaches across Guadeloupe, Martinique, Saint-Martin, Saint-Barthélemy and the Dominican Republic • A simple 0-5 score for every beach: green you go, red you skip • Tonton Sargasse's daily bulletin, straight talk with tomorrow's trend • Real-time votes from swimmers on site that fine-tune the scores • Smell level indication, because that's often the real problem • A home-screen widget: your destination's status at a glance HOW IT WORKS Every day Fangass aggregates public and official data (Météo-France, satellite imagery, regional oceanographic bulletins) and cross-checks it with reports from visitors on the beach. The result: fresh, local information every morning, verified by people with their feet in the sand. WHO IS IT FOR? Caribbean residents, vacationers, vacation rental hosts, beachfront restaurant owners: anyone who wants to know where to swim without crossing the island for nothing. Fangass is free, no account needed, no ads.
