Sargassum at Plage de Roseau (Capesterre-Belle-Eau): today's report
Light
Visible presence
Plage de Roseau opens the east coast of Basse-Terre, just north of Capesterre-Belle-Eau, where banana plantations run almost to the shore. Grey volcanic sand, coconut palms and a long, straight strip of coast make it a natural stop on the road that follows the island's windward side.
The page tracks sargassum at Roseau day by day. You get the rating for today, from 0 to 5, what it means on the ground, and a map placing the beach among its neighbours. Everything is reassessed each morning, so the call to come or to head elsewhere rests on current information.

What to know about this beach
Roseau looks due east, straight at the Atlantic, with nothing between the sand and open water. That is the textbook definition of a windward coast: easterly trade winds blow here for most of the year and push the sargassum mats that cross the ocean ahead of them. When a raft reaches the Antilles arc, this shoreline meets it before the sheltered west ever does.
The coastline runs long and largely unbroken, which changes how weed settles. It spreads over hundreds of metres instead of packing into a closed cove, and a shift in wind can carry it off nearly as fast as it arrived. Rivers draining the heights above Capesterre-Belle-Eau also stir the near-shore band. Two consecutive mornings can look very different, which is why the reading is taken daily.
Frequently asked questions
Why is Roseau Beach so exposed to sargassum?
It faces due east with open Atlantic in front of it. Trade winds drive drifting mats straight onto this stretch, so the east coast of Basse-Terre usually registers arrivals before anywhere else on the island.
How do I check Roseau before making the drive?
The FanGass map posts a 0 to 5 rating for Roseau every morning, with a short description of what has been observed. One look tells you whether to go or pick a backup beach.
Does the seaweed stay long on this beach?
On a shoreline this straight and open, deposits spread wide and a change of wind can clear much of it within days. Nothing is guaranteed either way, which is what the daily reading is for.
Which nearby beaches should I compare it with?
Other east-coast beaches of Basse-Terre share the same exposure and often move together. For a genuinely different picture, look at the leeward side of the island on the map before choosing.
