Last time I was in the area the sargassum seaweed was awful. It can be removed from the beaches but, depending on where it's removed, it continues to draw bugs and smells awful. If you're an ocean swimmer, the sargassum can be deep and wide enough to make that difficult.
Although it's been somewhat seasonal in past years, this year I understand that the sargassum has been pretty consistent in it's intensity.
If I were to stay in the area, I'd probably opt for a little north of Tulum and stay at Esencia on Xpu Ha Beach. That doesn't improve the sargassum, sadly, but when the water is clear the beach is stunning.
I'd be hard pressed to risk the Riviera Maya and much of the Caribbean until I knew the situation had improved.
