Zofemat crews have collected more than 2,800 metric tons of sargassum in Tulum this season, part of a cleanup the municipal government says it runs alongside the Navy, the state, and private hotels.
The figure matters because the beach is the product. Tulum's tourism economy rests on water that photographs turquoise, and seaweed left long enough to rot turns that water brown, sours the air with hydrogen sulfide, and moves guests from the shoreline to the pool. Everything the municipality is doing right now is a race against decomposition.
Castañón supervises Playa del Pueblo and names his partners
Mayor Diego Castañón Trejo walked Playa del Pueblo during a supervision visit to see the collection work in person. He described an operation coordinated across three levels of authority and the private sector, with the Secretaría de Marina, the Quintana Roo state government, and hotel operators all working the same stretch of coast.
"We are here today at Playa del Pueblo with Zofemat personnel attacking this extreme influx. We will not let our guard down, and we are doing this work in coordination with the Navy, the state government, and hotel owners," the mayor said, in remarks translated from Spanish.
The Navy's involvement is not new. Semar has led the federal response to sargassum in the Mexican Caribbean since 2019, working offshore with containment barriers and collection vessels while municipal crews handle what still lands. The division of labor is simple in theory. Stop what you can at sea, and shovel the rest.
Zofemat's numbers, 2,800 tons and more than 1,000 container trips
The volume reported by the Zona Federal Marítimo Terrestre covers only what its own personnel removed. It does not include what hotel crews pulled off their private frontage, which means the real total on the ground is higher than the municipal count suggests.
Moving that mass is its own logistical problem. Zofemat reports more than 1,000 container trips to transfer centers, each one a truck cycle that has to be scheduled, staffed, and fueled. Sargassum is heavy, wet, and full of sand, and it does not compact the way ordinary waste does. A ton of it fills far more space than a ton of household trash.
The hotel sector is running its own cleanup in parallel. Properties along the beach coordinate internal crews to clear their frontage, which keeps guest-facing sand workable and frees public crews to concentrate on open beaches like Playa del Pueblo, where nobody is paying a private brigade to show up at dawn.
Where the sargassum in Tulum goes after it leaves the sand
David Buchanan, director general of Zofemat Tulum, said collection is only half the job. The other half, and the one he described as a critical priority, is securing adequate final disposal sites for everything the trucks carry away.
His concern is leachate. As sargassum breaks down, it releases liquid that carries whatever the seaweed absorbed during its months at sea. Dumped on unprepared ground, that runoff can reach the aquifer, damage local vegetation, and affect coastal fauna across the Riviera Maya. Buchanan framed this as the difference between solving a problem and relocating it.
The geology under Tulum makes the stakes unusually literal. This is porous limestone, threaded with cenotes and underground rivers that feed both the drinking water supply and the reef system offshore. Anything that soaks into the ground here does not stay put. It travels.
Buchanan calls the season atypical for the Quintana Roo coast
Buchanan characterized current conditions as a completely atypical scenario for the Quintana Roo coastline, language that puts this season outside the range local crews plan for.
Sargassum arrivals in the Mexican Caribbean generally run from spring into autumn, with the heaviest weeks concentrated in the middle of that window. Municipalities budget crews and equipment against an expected curve. When the curve breaks, the shortfall shows up as seaweed sitting on the sand longer than it should, because there are not enough hands, trucks, or approved dumping grounds to move it at the speed it lands.
Crews stay out through the heaviest arrival months
The municipal government confirmed that work will continue without interruption through the period of heaviest arrivals, framing the effort explicitly as a defense of Tulum's tourism competitiveness. That framing is honest about the motive. The beach is an economic asset, and the ninth municipality is protecting it.
What the announcement does not resolve is Buchanan's disposal question. Collection capacity can be scaled with more crews and more trucks. Approved sites that can hold thousands of tons of decomposing organic matter without leaking into the aquifer cannot be improvised in a season. Until that piece is settled, every additional ton removed from the sand becomes a ton that has to go somewhere, and the honest measure of this operation will not be what leaves Playa del Pueblo. It will be what happens to it afterward.
Should Tulum be spending more on approved sargassum disposal sites than on beach collection itself? Join the conversation and share your perspective with us on Instagram and Facebook at @thetulumtimes.
