I was on the island last week, and I visited the far south end of Orient (past Papa) daily. The water was very calm and clear of saragassum all seven days I was there.

The downside is that there are no chairs/umbrellas to rent. However, for my visit, I rented a chair, umbrella, and cooler from Packlight Vacation rentals. The downside, of course, is that I had to drag the gear from the parking area to the beach area. IMO, it was worth it, as one day, the saragassum was HORRIBLE on the main beach, with the south-end completely clear.
