Cancún seaweed: where the beaches stay light

You can still go. For November, Cancún’s bay side, Costa Mujeres and Cozumel are expected light; Isla Mujeres, the open Hotel Zone coast, Puerto Morelos, Playa del Carmen and Tulum are expected moderate. Seaweed drifts in from the east, so shores that face north or west stay lighter.
