Sargassum at Cluny beach (Sainte-Rose): today's conditions
Clear
No worries
Cluny beach opens onto the north coast of Sainte-Rose, northwest of the village, facing the Atlantic. It marks the western edge of the Grand Cul-de-Sac Marin area, at the point where the shoreline loses its offshore protection and the sea arrives without anything in its way.
This page gives the sargassum situation at Cluny for the current day: the morning reading, a 0 to 5 rating that reduces it to one figure, and a map for comparing with other beaches around Sainte-Rose. The update is published every morning, before people set out.

What to know about this beach
Cluny occupies the Atlantic side of Sainte-Rose and faces north. Unlike the inner Grand Cul-de-Sac Marin, no reef screens the shore here: open ocean swell arrives intact, and swimming calls for caution, currents and breaking waves included.
For sargassum, that exposure cuts both ways. An Atlantic shore receives the mats carried by trade winds and by the current crossing the region before any sheltered coast does, and a northern aspect makes it responsive to swell out of the north as well as to winds that shift after a rainy spell. Yet the energy of the water matters too: where the sea works hard, stranded weed breaks up or floats off faster than it would in a quiet bay. Two consecutive days can look genuinely different here.
Frequently asked questions
Does Cluny get more sargassum than sheltered beaches?
Its drawback is openness. Facing the Atlantic with no reef offshore, it stands on the first line reached by drifting mats, and its northern aspect adds sensitivity to swell out of the north.
How do I check Cluny before making the drive?
Open this page on the morning itself: the map is recalculated daily and carries a 0 to 5 rating for the beach. Since Cluny sits away from the village, that habit saves a pointless round trip.
Can conditions change from one day to the next at Cluny?
Yes, faster than in an enclosed bay. The sea is active here, so a mat left yesterday may be lifted or broken apart, and a clear shore can take a fresh arrival overnight.
What alternatives are there around Sainte-Rose?
Beaches further east, behind the reef that closes off the bay, sit in a completely different exposure from Cluny. Comparing their daily ratings on the map takes only a few seconds.
