Sargassum Receding From Mexico’s Beaches, But Seaweed Still Impacting Travel

Travelers heading to Mexico’s Caribbean coast may see some improvement in one of the region’s biggest ongoing problems, but the sargassum season is far from over.

According to Mexico News Daily, sargassum has begun to recede from beaches across Quintana Roo after peaking in June and July. Quintana Roo Sargassum Monitoring Network director Esteban Amaro Mauricio said the decline should become more noticeable in September and October.

International travelers heading to popular destinations such as Cancun, Playa del Carmen, and Tulum should continue checking local beach conditions before visiting, as some areas remain heavily affected.

Tulum and Mahahual are still dealing with significant accumulations, while Playa del Carmen has recently seen less sargassum. Puerto Morelos, meanwhile, had been relatively clear before experiencing a significant influx this week.

According to Reuters, around 110,000 tons of sargassum have been collected across Quintana Roo so far this year, with Amaro projecting the total could reach about 150,000 tons. That would be well above the estimated 94,000 tons collected last year.

Recent monitoring showed dozens of beaches under red alerts for excessive sargassum, particularly in southern Quintana Roo. The amount reaching individual beaches can change rapidly based on ocean currents, wind and weather conditions.

Amaro expects sargassum arrivals to become minimal during November and December, although the algae could return as early as January 2027. That would be an unusually early start compared with previous years, when the season more commonly began in April or May.

Mexican officials are also stepping up efforts to keep the stinky seaweed from reaching the shoreline. The federal government announced a major investment in July to strengthen collection in open water and along beaches, while expanding efforts to process and reuse the material.
