Top developments
Quintana Roo breaks sargassum record for second consecutive year
Quintana Roo has collected 133,646 tons of sargassum so far in 2026, according to the latest SEMA (Secretaría de Ecología y Medio Ambiente) report, exceeding the state's previous historical maximum. La Jornada reports the state set a record for landings for the second year running — 2025 saw 93,000 tons. Playa del Carmen is the hardest-hit municipality, concentrating 44,547.64 tons, or 33.3% of the state total.
Cancún "breathes" as September landings ease — but wind shifts loom
Sargassum volume collected on beaches in Benito Juárez municipality (Cancún) decreased during September, according to Arturo Quintero Díaz, director of Playas y Pozos, as the municipality approaches the end of its intensive response period. However, authorities fear changing wind patterns could reverse the reprieve.
Still 135 of 140 monitored beaches with sargassum presence
Despite the easing trend, SEMA's sargassum traffic-light update (Monday, Sept 21) showed 135 of 140 monitored beaches in the state's north and south zones still with sargassum, at levels ranging from low to excessive — a situation that continues to worry hoteliers.
Wedding tourism takes a hit; hotel sand-revival programs expand
Concanaco Servytur estimates sargassum has spoiled roughly 10,000 wedding reservations in the Mexican Caribbean, and reports 11 initiatives with industrial-use potential for the recovered biomass. Meanwhile, hotels like Moon Palace are running environmental programs that separate sargassum, seagrass and sand, sending mixed material to a treatment center to revive beach sand.
Playa del Carmen seeks federal permit to return cleaned sand to beaches
Sargassum cleanup in Playa del Carmen has stripped sand from the beaches; the city is now seeking a federal permit to return the recovered sand as US$1.6 billion in hotel construction projects advance. The outcome matters for beach-capacity restoration heading into the high season.
Local view
Quintana Roo Hoy reports that hoteliers and authorities remain tense despite the easing recale, with 135 of 140 beaches still showing sargassum presence and pressure on both public budgets and private clean-up crews. Prensa Mercosur frames the month as "Cancún respira" — a genuine but fragile recovery driven by the municipal beach management team.
