About this app

Which beaches in Guadeloupe, Martinique, Saint-Martin, Saint-Barthélemy, or the Dominican Republic are free of sargassum seaweed today? Fangass tells you every morning, beach by beach.

WHAT YOU'LL FIND IN THE APP
• A live sargassum map covering 154 beaches in the Antilles and the Caribbean
• A simple 0-to-5 rating for each beach: green means go, red means avoid
• Uncle Sargassum's daily report, frank and straightforward, with the forecast for tomorrow and the day after
• Votes from beachgoers on site, which refine the ratings in real time
• Odor indicator, because that's often the real problem
• A widget for your home screen: the sargassum weather for your destination at a glance
• Sargassum areas detected offshore by satellite imagery

HOW IT WORKS
Every day, Fangass aggregates public and official data (Météo-France, satellite imagery, regional oceanographic reports) and cross-references it with feedback from visitors on site. The result: fresh, local information every morning about sargassum seaweed strandings, verified by those with their feet in the sand.

DESTINATIONS COVERED
• Guadeloupe: 47 beaches, from La Caravelle to Grande-Anse, including Marie-Galante, Les Saintes, and La Désirade
• Martinique: 44 beaches, from Les Salines to Anses-d'Arlet
• Saint-Martin: 20 beaches, from Orient Bay to Mullet Bay
• Saint-Barthélemy: 11 beaches
• Dominican Republic: 32 beaches, from Punta Cana to Bahía de las Águilas

WHO IS IT FOR?
West Indian residents, vacationers, seasonal rental owners, beachfront restaurant owners: anyone who wants to know where to swim peacefully without having to travel across the island for nothing.

Fangass is free, requires no account, and is ad-free.
