Playa del Carmen is facing a severe environmental and economic challenge in 2025 due to an unprecedented influx of sargassum seaweed. The excessive accumulation of this algae is impacting the local economy, marine ecosystems, and public health.
The sargassum season, which typically runs from April/May to August, is expected to be particularly intense this year. Experts are forecasting more frequent and substantial arrivals of sargassum along the coast. As of mid-April, authorities had already collected over 10,000 metric tons of sargassum in Playa del Carmen, Puerto Morelos and Othón P. Blanco. Daily collection rates have reached approximately 200 tons. To combat this, the local government has deployed a team of 101 people to clean the beaches daily.
The consequences of the sargassum surge are far-reaching. The decaying seaweed emits a foul odor, deterring tourists and impacting local businesses. Marine life is also suffering, as the algae blocks sunlight, harming coral reefs and seagrass beds. The decomposition process depletes oxygen in the water, endangering various species. Tourism operators are adapting by offering alternative activities, as many tourists seek experiences beyond the sargassum-covered shorelines.
