Sargassum at Baie Orientale: today's beach report

Today, September 1

Light

Some weed

Baie Orientale runs along the Atlantic side of Saint-Martin, on the French part of the island. It is the longest stretch of sand in that half, wide open to the ocean and closed off far out by a line of small cays. That exposure is exactly why sargassum comes up so often here.

This page tracks sargassum at Baie Orientale day by day: a rating from 0 to 5, a plain reading of what the beach looks like, and a map placing it next to the other spots we follow on Saint-Martin. Everything is reviewed each morning, before beach hours begin.

What to know about this beach

Facing due east on the Atlantic coast, Baie Orientale takes the trade winds head on. Sargassum rafts drifting in from the tropical Atlantic are pushed straight onto this windward shore, which makes wind strength and easterly swell the two things worth checking here. A raft sitting offshore in the morning can be against the sand by mid-afternoon.

The cays and shallow banks offshore soften the swell and keep the water calmer close in, but they do not filter the weed: whatever slips past can pile up along the sand and gather in the corners of the bay. Because the beach is long, landings are rarely even, and one section can be loaded while another stays usable. The daily rating covers the bay as a whole.

Frequently asked questions

Why does Baie Orientale get sargassum more often than other beaches here?

It sits on Saint-Martin's Atlantic side and faces due east, so the trade winds and open-ocean swell drive rafts directly onto the sand. The leeward beaches on the west coast are far better sheltered.

How do I check the beach before heading over?

Open the FanGass page for Baie Orientale in the morning: it gives a rating from 0 to 5, a short summary of what was observed and a map of the island, refreshed every single morning.

Is there a quieter season for sargassum here?

Arrivals usually cluster from spring through late autumn and vary a lot from year to year. Winter tends to be calmer, though nothing is guaranteed, so the daily reading is what actually settles it.

Where can I go if the bay is covered?

West coast beaches such as Friar's Bay, Anse Marcel and Baie de Grand-Case sit on the sheltered flank of the island and see much less weed. Check their ratings before crossing over.

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.
