Mexico’s Battle Against Sargassum: Empty Beaches and Stench

According to an Agence France-Presse (AFP) field report, the Mexican Navy and local governments collected roughly 100,000 tons of sargassum across the Riviera Maya and Tulum during the first semester of the year. Despite deploying 27 specialized vessels, barriers, and manual beach cleanup crews to combat the invasive seaweed arriving since 2011, coastal tourism operations face severe economic strains and pungent odors that drive visitors away from once-pristine Caribbean beaches.

Naval Operations and Mechanical Collection at Sea

The Mexican Navy relies on a fleet of 27 vessels operating along the Riviera Maya and Tulum coastlines to intercept sargassum before it reaches the shore. According to operations commander, contralmirante Topiltzin Flores, crews utilize a specialized 300-ton capacity ship alongside smaller amphibious craft to scoop the seaweed from open water.

The primary collection vessel uses a motorized front ramp equipped with a large mechanical belt. This system lifts floating seaweed from the water’s surface and deposits it directly into an interior hopper, functioning similarly to a mechanical harvester.

Collection Volume Comparisons: 2024 Versus Previous Years

Data provided by operational authorities show an intensification of the seaweed influx. During the first six months of the year, government personnel and local agencies gathered approximately 100,000 tons of sargassum.

This total surpasses the 92,782 tons collected in 2025, highlighting what officials term an exceptionally intense season that demands heightened collection efforts.

Economic Impacts on Local Tourism and Hospitality

While government collection totals rise, coastal businesses report steep downturns in customer volume and revenue. According to Playa del Carmen waitress Azul Lucero, restaurant patronage has plummeted from up to 400 daily clients during clean-water periods down to roughly 50 customers.

Hotel occupancy rates across the region currently hover between 55% and 70% according to the destination, sitting well below the historical 90% highs recorded during peak seasons a decade and a half ago. Workers like Playa del Carmen cook Tere May report that sulfurous odors akin to rotten eggs leave entire properties, such as her 24-room hotel, completely empty of guests.

Government Stance and International Tourism Metrics

Federal officials maintain that overall foreign tourism numbers remain strong despite localized environmental challenges. During a press briefing, President Claudia Sheinbaum stated that international travel shifts stem from commercial jet fuel costs rather than the seaweed invasion, adding that the country has avoided major economic losses under an integrated strategy uniting government agencies and hoteliers.
