Sargassum at Plage de Sainte-Marie: today's conditions
Light
Some weed
Plage de Sainte-Marie sits just below the town of the same name, on the Atlantic side of northern Martinique. It faces northeast, straight out to open water, along a stretch of coast where sargassum has to be read day by day.
This page covers the practical side before you go: today's sargassum report for Sainte-Marie, a 0 to 5 rating that sums up the situation at a glance, and a map placing the beach within its surroundings. Everything is refreshed each morning, so your plan rests on recent observations rather than last week's photos.

What to know about this beach
Sainte-Marie lies on Martinique's windward shore, the side that takes the easterly trade winds and the Atlantic swell head on. Sargassum rafts drifting in from open ocean reach this coastline before anywhere else on the island, and the beach's northeast aspect puts it directly in that path, with no headland or island shielding it.
The bay looks out to Îlet Sainte-Marie, joined to the shore for part of the year by a sand tombolo. That sand bridge and the shallow water around it create pockets where weed can settle and linger once an influx reaches the area, while a fully open shoreline may clear faster. Along the northern Atlantic coast, intensity shifts from one cove to the next, so a single day's reading tells you more than any seasonal rule.
Frequently asked questions
Why does Plage de Sainte-Marie get sargassum?
It opens northeast onto the Atlantic, the side the trade winds push against. Rafts carried in from open water reach this shore first, with no island or point to deflect them beforehand.
How do I check the beach before driving over?
Open the FanGass map, updated every morning. It gives Sainte-Marie a 0 to 5 rating alongside the day's observed conditions, which is enough to decide whether to keep your plan or pick another spot.
Is there a worse time of year here?
Influxes tend to cluster between spring and autumn across the Caribbean, though nothing holds firm from one day to the next. On this coast, yesterday's wind and swell often count for as much as the calendar.
Does the tombolo to Îlet Sainte-Marie change anything?
The sand bar linking the islet partly encloses the water behind it. When sargassum drifts into that pocket it can stay put longer than on a beach front that remains fully open to the sea.
