According to a report from the Secretariat of Environment (SEMA), from April to August, 124,852 tons of sargassum have been removed, representing 29,069 more tons than in 2025 and revealing the five municipalities with the highest concentration of sargassum.
With less than a month remaining before the end of the sargassum season, Playa del Carmen has the highest volume of the macroalgae removed, followed by Cancún, Puerto Morelos, Tulum, and Mahahual.
The Secretariat of the Navy has installed 12,855 meters of barriers in key and strategic locations, as sargassum affects 1,176 kilometers of coastline. However, the Navy expects to reach 16,030 meters of barriers as part of the 2026 National Strategy Against Sargassum announced by the government of Claudia Sheinbaum.
Currently, through federal and state efforts, 42,063 tons of sargassum have been removed from the coastline of Playa del Carmen; 29,899 in Cancún, while 17,111 tons have been removed in Puerto Morelos. In Tulum, 16,471 tons have been removed, and in Othón P. Blanco, 14,013 tons; in Isla Mujeres, 3,877 tons of sargassum have been reported as removed, 1,375 in Cozumel, and 39 in Lázaro Cárdenas.
As reported by REPORTUR.mx, engineer Guillermo Alvarado, who specializes in petroleum chemistry and green biotechnology, recently indicated that sargassum control should not be limited solely to collection; it is also related to the conditions that promote its proliferation, including inadequate wastewater treatment, which creates favorable conditions for excessive algae growth.
