Cozumel Collects Up to 10 Tons of Sargassum Daily as Seaweed Arrivals Spike

Cozumel, Quintana Roo — An increase in sargassum along Cozumel’s eastern coast has prompted intensified daily cleanups, with crews hauling between six and 10 tons of the seaweed each day to prevent harm to tourism and the ecosystem during the peak summer vacation season.

Gerardo Can Novelo, director of the Federal Maritime Terrestrial Zone (Zofemat), said cleanups run daily from 7 a.m. to 1:30 p.m., focusing on Chen Río, Mezcalitos, and Punta Chiqueros, where wind and currents have driven more seaweed ashore in recent days.

Operations also include measures to protect sea turtle nesting season. Before removing the macroalgae, crews coordinate with the Ecology Department to locate nests and avoid damage from machinery or manual cleaning, Can Novelo explained.

Despite the increased arrivals on the east side, public beaches that draw the most tourists remain sargassum-free, allowing visitors and residents to enjoy them without the nuisance of accumulated seaweed.

The Quintana Roo Sargassum Monitoring Network reported in its weekly update that 68 of 140 monitored beaches in the state have sargassum at varying levels, showing the phenomenon continues to affect the coastline during the holiday period.
