Sargassum at Anse Corps de Garde (Sainte-Luce): today's report
Clear
Dive in
Anse Corps de Garde spreads west of Sainte-Luce village, on the Caribbean coast of southern Martinique. It is the longest beach in the commune, lined with coconut palms and shelving gently into the water, which is why families tend to settle here for the afternoon.
This page gives the sargassum picture for that specific beach: what was recorded this morning, a rating from 0 to 5, and a map that places Anse Corps de Garde alongside the neighbouring stretches of coast. The update lands each morning, before the hour when most people load the car.

What to know about this beach
The beach opens due south, facing away from the easterly trade winds that carry sargassum rafts across from the Atlantic. Martinique's windward shores, on the east, take the first load; Sainte-Luce sits well downstream of that corridor.
What sets this beach apart from the small coves nearby is its shape. The bay is wide and only lightly enclosed, so when an influx rounds the southern tip and works its way up, it meets a long front to settle on, yet water movement also clears the deposit faster than at the back of a tight inlet. Conditions can therefore shift from one day to the next, and differ between one end of the sand and the other depending on where the wind drives the mats. The morning rating covers the beach as a whole.
Frequently asked questions
Why does Anse Corps de Garde receive less sargassum?
Its Caribbean-facing position keeps it off the direct path of weed driven by the trade winds. Landings are rarer than on the Atlantic coast, though a large influx travelling up from the southern tip can still reach it.
How do I check before driving down with the family?
The FanGass map posts a rating from 0 to 5 for Anse Corps de Garde every morning. A glance over breakfast tells you whether the plan holds or whether another beach makes more sense.
Does the whole beach get covered at once?
Not usually. On a stretch this long, mats pile up where the wind drives them, often against one end. The daily rating summarises the site, so walking a few hundred metres on arrival still pays off.
Which months bring the most weed here?
The heaviest stretch runs from spring to late summer, with big swings between years. Episodes do occur in the drier months as well, but they are generally shorter and clear more quickly.
