Live map, a 0-to-5 score, and a plain-language verdict: go, or pick another spot.

Sargassum in Guadeloupe today

Updated June 17

A small break is shaping up, but the east side stays a mess: north-east Grande-Terre and east Basse-Terre getting hit hard, south Grande-Terre touched in spots. Leeward Basse-Terre coast stays clean, plan B is Deshaies or Malendure. Désirade, Marie-Galante and Les Saintes much calmer.

The live sargassum map of Guadeloupe

The map below shows today’s status for every monitored beach, with a colored dot from green (clear) to black (evacuated zone). Turn on the “Offshore sargassum” layer to see the satellite-detected rafts drifting off the archipelago — handy to anticipate landings over the next few days depending on currents and trade winds.

Which beaches in Guadeloupe are most affected?

Landings mainly hit the windward, Atlantic-facing coasts: the south coast of Grande-Terre (Sainte-Anne, Saint-François, Raisins-Clairs), the east coast of Basse-Terre (Capesterre-Belle-Eau, Trois-Rivières) and the head of the Cul-de-Sac Marin (Petit-Bourg, Sainte-Rose).

The Caribbean (leeward) coasts are usually the most reliable fallback: Deshaies (Grande-Anse), Pointe-Noire and Malendure in Bouillante are generally spared. Marie-Galante, Les Saintes and La Désirade vary with the incoming rafts.

How to read a beach’s status

Each beach gets a 0-to-5 score and a color. Green (0-1): clear, go for it. Yellow (2): some seaweed, swimmable but not perfect. Orange (3): moderate landing, visibly present. Red (4): heavy landing, it stinks, avoid. Black (5): evacuated zone, stay away. A smell index (none / light / strong) completes the score, because the rotting smell is often what ruins the outing.

When is sargassum season in Guadeloupe?

Sargassum landings mostly occur from March to October, often peaking between April and August. But nothing is fixed: it all depends on the rafts drifting in from the tropical Atlantic, the currents and the wind direction. A clean beach one morning can receive a landing 48 hours later — which is why a daily update beats a seasonal average.

Where does FanGass’s data come from?

Every day FanGass reads the official monitoring bulletins (Météo-France Guadeloupe and their maps, NOAA AOML, the University of South Florida monthly outlook, regional bulletins), cross-checks them against satellite imagery of the offshore rafts, then distills it all into a clear per-beach score. On-the-ground reports from users adjust the scores live when several reports agree. The service is free, offered by the Katchak agency.

Frequently asked questions

Is there sargassum in Guadeloupe right now?

Today’s beach-by-beach status is shown on the map and list above, updated every morning. Green dots mark the clear beaches, orange/red dots the ongoing landings.

Which beaches should I avoid because of sargassum in Guadeloupe?

During heavy landings, the south coast of Grande-Terre (Sainte-Anne, Saint-François) and the east coast of Basse-Terre (Capesterre, Trois-Rivières) are the most exposed. Always check today’s score — the situation changes fast.

Which beaches in Guadeloupe are free of sargassum?

The Caribbean (leeward) coasts are often spared: Deshaies and Grande-Anse, Pointe-Noire, Malendure in Bouillante. Good fallbacks — but confirm on the map on the day.

Is sargassum dangerous?

As it decomposes, sargassum releases hydrogen sulfide (H₂S), a rotten-egg smell that is not advised for sensitive people (asthma, infants, pregnant women) during heavy landings. That is why a smell index accompanies every beach.
