Sargassum Returns Early to Puerto Morelos: What Locals Need to Know

Sargassum season has arrived unusually early in 2026, with Puerto Morelos already experiencing accumulations along our beautiful coastline. This brown seaweed typically appears later in the year, but  shifting ocean currents have altered its patterns.

 

Current Situation in Puerto Morelos

 

The Sargassum Monitoring Network and regional reports confirm early 2026 sargassum arrivals affecting Quintana Roo beaches, including Puerto Morelos, with the Mexican Navy reporting approximately 178 tons collected across affected areas like Puerto Morelos and Playa del Carmen earlier this month due to strong winds.

 

Local hotels and beach clubs have already mobilized cleaning crews. Early morning removal efforts help keep beaches presentable for visitors, though accumulation becomes more visible as the day progresses.

 

Health and Environmental Concerns

 

The decomposition of sargassum poses risks we should all be aware of. Scientific studies have found that sargassum leachate contains concerning levels of metals including arsenic and cadmium.

 

When decomposing, the seaweed releases hydrogen sulfide and ammonia gases. These can cause irritation to eyes, nose, and throat, especially for those with respiratory conditions. The porous limestone beneath our feet means contaminants can quickly reach our aquifer if sargassum isn't properly managed.

 

Community Response

 

Puerto Morelos businesses have joined regional efforts, with hotels installing barriers and hiring staff, alongside municipal cleaning and year-round Navy-led collection strategies now made permanent following early 2026 arrivals.

 

Municipal workers begin cleaning at dawn, focusing on the most popular beach areas. Some local entrepreneurs have explored innovative uses for collected sargassum, including composting and artisanal products.

 

Looking Ahead

 

Forecasts suggest 2026 could see continued heavy sargassum similar to the severe 2025 season (with first major landfalls in March–April), depending on ocean conditions, though accurate predictions will emerge later in 2026.

 

For Puerto Morelos residents, staying informed about daily sargassum levels will be important. The Sargassum Monitoring Network provides regular updates that can help plan beach activities. Morning hours typically offer the cleanest beach conditions.

 

While the early arrival is concerning, our community has developed better systems to manage this challenge over recent years.

 

Puerto Morelos continues to offer beautiful beach experiences, especially with the coordinated efforts of local businesses and authorities.
