Quintana Roo Faces 50% Delay in Sargassum Barrier Installation

Cancún, Quintana Roo — Quintana Roo’s strategy to control sargassum seaweed is facing a critical logistical challenge, with nearly half of the planned marine barriers still not installed as the arrival season begins. The state’s Ecology and Environment Secretariat (SEMA) reports only 48% progress on its 2026 plan, leaving key tourist destinations vulnerable.

Of the 15,000 meters of infrastructure planned, only 7,200 meters have been deployed. This leaves 7,800 meters pending, putting high-impact municipalities like Tulum, Cancún, Puerto Morelos, and Playa del Carmen on alert due to frequent seaweed influxes.

Pending Barrier Distribution by Municipality

According to official SEMA data, the pending barrier deployment for the coming weeks is distributed as follows:

• Playa del Carmen: 2,400 meters pending.
• Tulum: 2,300 meters pending.
• Puerto Morelos: 2,300 meters pending.
• Mahahual: 400 meters pending.
• Cancún: 400 meters pending.

Climate Factors and 2026 Forecast

The next priority intervention point is Tulum; however, authorities warn that the success of the work depends on weather conditions. A delay in technical deployment could leave coasts unprotected during May and June, when the peak of the phenomenon is expected.

Scientists and authorities estimate the arrival of at least 120 tons of sargassum this year. The lack of barriers not only threatens the state’s tourism image but also increases operational cleaning costs and risks the health of coastal ecosystems.
