Cancun is presently enjoying beaches with minimal sargassum presence; however, projections indicate a substantial increase in the coming months. The Sargassum Monitoring Network has issued a warning regarding an impending significant grounding of the macroalgae that could severely impact the coastline of Quintana Roo.

Current Sargassum Conditions
Esteban Amaro, director of the Monitoring Network, reported that the arrival of sargassum occurred nearly two months earlier than usual this year, particularly affecting the southern region of the state. “The anticipated sargassum levels for 2025 are notably higher than what has been observed in the past three years. To illustrate, over 40,000 tons were collected last year, and current forecasts suggest this figure will be surpassed,” stated Amaro.

Presently, the most significant sargassum accumulations are being recorded in areas such as Mahahual, Xcalak, the Sian Ka’an Biosphere Reserve, Tulum, and the eastern coast of Cozumel. In contrast, Playa del Carmen and the western coast of Cozumel have experienced intermittent arrivals, while Cancun, Contoy, Holbox, and Isla Mujeres have reported minimal sargassum levels to date.
Anticipated Increase Based on Satellite Imagery
Despite the current favorable conditions in certain areas, satellite images present a concerning outlook for the approaching months. “We anticipate more intense and frequent groundings along the entirety of the coastline,” cautioned Amaro. As part of proactive measures, the Navy and the state government have deployed 9,500 meters of anti-sargassum barriers.

The director of the Monitoring Network emphasized the critical role these barriers will play in safeguarding the most frequented beaches in the Mexican Caribbean. He also urged authorities to enhance their strategies in preparation for a likely challenging scenario.
Comprehensive Sargassum Management Strategy Underway
Authorities at all three levels of government recently initiated a comprehensive strategy focused on the monitoring, containment, collection, and disposal of sargassum. This marine macroalgae, linked to climate change, continues to affect the Caribbean region, resulting in considerable economic and ecological consequences.
While Cancun currently benefits from manageable levels of sargassum, allowing for enjoyable beach experiences, the anticipated influx necessitates vigilance and proactive management. Travelers planning visits in the coming months should remain informed about the evolving situation.

Alternative Destinations with Low Sargassum Levels
For travelers prioritizing sargassum-free beaches, the following destinations offer potential alternatives:
- Bacalar: Renowned for its stunning freshwater lagoon, the “Lake of Seven Colors,” Bacalar remains unaffected by sargassum.
- Isla Mujeres (West Coast): The western beaches of Isla Mujeres typically experience significantly lower sargassum levels compared to the eastern side.
