Sargassum in Quintana Roo has reached moderate to excessive levels on 76 beaches—including Cancun—as cleanup crews race to protect tourism and coastal ecosystems.
A recent survey from the Quintana Roo Sargassum Monitoring Network and the Sargassum Citizen Observatory shows 76 out of 100 beaches on the state’s Caribbean coast now face moderate to excessive seaweed influx. The surge spans from the hotel zone in Cancun down through Riviera Maya and as far as Tulum, prompting daily cleanup efforts by authorities and private operators.
According to Sunday’s report, 17 beaches registered moderate sargassum arrivals, nine showed abundant levels, and a striking 50 beaches hit the red “excessive” threshold on the Observatory’s traffic-light scale. Cancun’s main coastline remains among the hardest hit, with several shorelines reporting more than a cubic meter of seaweed per linear meter of beach.
“Local teams work before dawn and into the evening to clear sargassum,” said María López, coordinator for the Citizen Observatory. “Our crews use tractors, hand rakes and floating barriers to keep the beach open for visitors. But with this volume, it’s a race against the tide.”
The affected area covers popular destinations across the state: from Punta Cancún and Playa Chac Mool in the north, through Puerto Morelos and the Cozumel ferry zone, to Playa del Carmen and the archaeological beaches near Tulum. In many spots, thick mats of brown algae wash up daily, threatening hotel-zone operations and small businesses that rely on sun-and-sand tourism.
Environmental scientists warn that the current bloom results from a mix of factors. Warmer Caribbean waters fueled by climate change can boost sargassum growth. Nutrient runoff from rivers and agricultural lands farther south may also feed the algae, while shifting currents concentrate blooms along coastal reefs.
Dr. Carlos Ruiz of the National Marine Institute explained, “Moderate levels can benefit local ecosystems by providing habitat for fish. But excessive accumulations block sunlight, alter water chemistry and can harm sea life when decomposing.” He noted that trapped sargassum can lower oxygen levels in nearshore waters, stressing coral reefs and seagrass beds.
Tourism officials remain optimistic. “We know how to handle this,” said Jorge Martínez, head of the Quintana Roo Tourism Board. “Our hotels and beach clubs have protocols in place. We share real-time data with government agencies so they can deploy cleanup crews where they’re needed most.”
Still, some small operators struggle to keep pace. “Last week we cleared the sand by hand,” recounted beach club owner Ana Gómez. “Today I had to pause service twice because the tide brought in new piles.”
State officials stress that public cooperation helps. Observers encourage beachgoers to report dense sargassum via a dedicated hotline and to avoid dragging heavy mats back into shallow water. Each report lets crews target hotspots before they grow unmanageable.
As the summer season proceeds, authorities and scientists will continue weekly assessments. The goal: keep Quintana Roo’s white-sand beaches clear, protect marine ecosystems, and safeguard the region’s vital tourism economy.
