Sargassum at Cap Macré (Le Marin): today's beach report
Moderate
Moderate
Cap Macré marks the Atlantic edge of Le Marin, on the southeastern coast of Martinique. This is the wild side of the shoreline, followed by the coastal path that links the capes, with sandy coves separated by rocky points and very little in the way of facilities.
This page tells you where sargassum stands at Cap Macré today: what has been observed, a 0 to 5 rating for comparing it with other sites, and a map of the southern Atlantic sector. The check is repeated each morning, before people set off for the day.

What to know about this beach
Two things shape this coast. The first is which way it looks: the cape faces east, out towards the open Atlantic that the trade winds cross with rafts of seaweed in tow. The second is the shape of the shoreline itself, a run of headlands and deep coves that act as traps for whatever the sea carries in, while the rocky points stay swept.
Scale therefore matters as much as the date. Two neighbouring coves at Cap Macré can look quite different on the same day, depending on wind angle and the depth at their mouth. On a shoreline with little upkeep, a deposit is not cleared away quickly and may dry where it lands.
Frequently asked questions
How exposed is Cap Macré to sargassum?
The cape opens east onto the Atlantic, the first coast to meet rafts carried by the trade winds. Its deep coves also hold incoming weed more readily than a straight, open shoreline would.
Is it worth making the trip on a given day?
Check the 0 to 5 rating on the FanGass map before you leave. Cap Macré takes some driving and walking to reach, so a look on the morning itself saves a wasted journey.
Can I find a clearer cove nearby on foot?
Often yes. The coves follow one another along the coastal path and do not share the same opening, so walking to the next one can be enough. Compare neighbouring ratings on the map first.
When do arrivals peak on this coast?
Spring and summer account for most episodes along the Atlantic front. Cooler months are usually quieter, without any guarantee, which is why the sector is assessed again every morning.
