Anse l'Étang, Tartane: where sargassum stands today
Moderate
Visible weed
Anse l'Étang sits a few minutes from the village of Tartane, on the northern side of the Caravelle peninsula in La Trinité. The bay opens eastward and its water is calmer than the more exposed coves nearby, which is why swimmers and families gravitate to it.
This page gives sargassum at Anse l'Étang for today: a 0 to 5 rating, the beach marked on the Martinique map, and the trend across the Trinité Atlantic stretch. The reading is rebuilt every morning rather than left standing from the day before, so what you see belongs to today.

What to know about this beach
Two things shape sargassum here. The beach belongs to the Atlantic side of Martinique, the side that meets the trade winds head-on, and its eastward opening puts it in line with rafts drifting in from open water. At the same time, rocky points frame the cove and take some of the punch out of the swell.
That shelter is good news for swimming and mixed news for seaweed. Water that moves less also flushes less, so anything that clears the mouth of the bay tends to be pushed toward the back of it rather than dragged out again. On a given morning, this beach can therefore read differently from a fully open cove only a few hundred metres away.
Frequently asked questions
How exposed to sargassum is Anse l'Étang?
It sits on the Atlantic side, so it is in line with rafts pushed by the easterly trades, but the headlands framing the cove soften the swell. Real exposure, with calmer water than the open beaches next door.
How can I check the beach on the day itself?
The FanGass map gives Anse l'Étang a 0 to 5 score for the day, rebuilt every morning. Check it before you leave rather than relying on yesterday, since one day to the next can look very different.
Why does seaweed sometimes linger in this bay?
The cove shape slows water exchange. Whatever enters from the east gets pushed toward the back of the bay, and without a shift in wind direction it can stay there for several days.
Where else can I look if the score is high?
Neighbouring Caravelle coves share the same exposure, so expect similar numbers. For a genuinely different pattern, check a Caribbean-side beach in Martinique, sheltered from the easterly flow by the island itself.
