Go for it

East of the village of Sainte-Luce, Anse Gros Raisin opens onto the Caribbean side of southern Martinique, its sand backed by the sea grape trees the name refers to. This page gives the current picture: sargassum at Anse Gros Raisin today, a rating from 0 to 5 and a map of the Sainte-Luce coast.

Everything is recalculated at first light, ahead of the day's first decisions. You will see whether the shore is clear, whether rafts are drifting off the cove, or whether a line of weed came in overnight, with the previous days shown so the trend is visible.

What to know about this beach

This cove belongs to the leeward Sainte-Luce coast, facing the Caribbean Sea. Sitting downwind of the trade winds puts it off the main track: rafts ride the easterly flow and unload on the exposed shores first. Planning a stay here is not the same exercise as on the exposed southern coast, where a landing is a daily possibility in season.

Less affected is not out of reach. When the circulating volume is high, patches round the southern tip of the island and travel along the sheltered coastline. The due-south opening of Anse Gros Raisin leaves it facing that coastal transit, while the points closing it on either side block whatever would arrive from the east. The morning rating is what that combination produces on the day.

Frequently asked questions

Why does Anse Gros Raisin see less sargassum?

It lies on the leeward Caribbean shore. Rafts driven by the easterly trade winds hit the exposed coasts first, and only part of that mass rounds the south of the island and travels up this side.

How can I check the cove before setting out?

The map on this page is rebuilt every morning and gives Anse Gros Raisin a rating from 0 to 5. You get today's state plus the previous days before you decide to make the drive.

How does it compare with the Sainte-Luce town beach?

Both share the same sheltered position and sit a few minutes apart. The town beach has the seafront and its shops, this cove stays quieter. Each one carries a daily rating, so the choice can be made the same morning.

When are arrivals most likely along this coast?

Episodes usually run from spring through to autumn, with an intensity that changes from year to year. On this sheltered coast they stay irregular, which is why a morning reading beats any calendar.

Methodology & transparency — FanGass is a free service published by the Katchak agency and created by Morgan Haillus. Every morning, each beach’s 0-to-5 score is recomputed by cross-checking official bulletins (Météo-France, NOAA, University of South Florida), satellite imagery of the offshore rafts, and on-the-ground user reports.
