Sargassum in Cozumel: common questions
Does Cozumel get sargassum?
Very little. The resorts and dive shops line the leeward west coast, so the seaweed drifts past on the island's east side and the beaches you'll use stay reliably clear — even in heavy years.
Is there seaweed in Cozumel right now?
Almost certainly minimal on the west-coast resort and dive beaches — check the live score above. Cozumel is one of the most dependable clear-water spots on the Mexican Caribbean.
When is sargassum season in Cozumel?
There isn't a meaningful one on the leeward west coast. Only the wild, undeveloped east side of the island ever sees notable amounts.
Which Cozumel beaches are clearest?
The west-coast strip south of town — fronting resorts like the Presidente InterContinental, Secrets Aura and Iberostar Cozumel — stays clear; the east/windward side is where any sargassum lands.
