Foul-Smelling Sargassum Invades Caribbean Beaches: What Planners Need to Know
This dense, brown seaweed, which is experiencing its worst year yet, is already wreaking havoc on beaches throughout the Caribbean. The month of May saw an explosion of the nasty-smelling brown seaweed known as sargassum in the Atlantic Ocean, increasing from 31 million metric tons in April to 37.5 million — the largest amount since monitoring began in 2011. The bloom, which typically runs from April to October, is already blanketing beaches from Puerto Rico to the Yucatan Peninsula, which includes Cancun, Tulum, and Playa del Carmen. These island-like masses are expected to continue their spread in June, invading the western Caribbean, Gulf of Mexico, Florida, and the beaches along the Southern U.S. coastline. Sargassum is a form of algae that releases hydrogen sulfide and ammonia, which can be dangerous to pregnant women and people with respiratory issues. The tiny sea creatures that bury themselves in the seaweed can cause rashes and blisters if they come in contact with skin. It's also a nuisance for resorts, and makes it difficult, if not impossible, for planners to host beach activities and hold waterfront events because of the smell. Mexico is actively addressing sargassum by focusing on four dozen beaches along the Yucatán Peninsula and Caribbean coast. Punta Cana has invested in barriers to prevent seaweed from reaching the shore. However, smaller Caribbean islands without the budget to address this issue are leaving the cleanup to the individual hotels. Some resorts are even installing their own barriers, such as the new AVA Resort Cancun, which just hosted the annual IRF Invitational this week. What Can Planners Do? The first step for planners is to get informed, said Kimberly Ruby, client engagement manager, marketing, at Canada Life Reinsurance, who began researching beach resorts for a vacation and could not find a single property that was addressing the issue. 'Properties need to make guests aware. It's like ADA concerns. I'd like to know ahead of time that your elevator is down. I can't make a decision if I don't know about it.' There are many ways planners can be affected. 'If I select a venue for a site visit and then see the sargassum — and smell it — I've wasted time and money visiting,' she said. 'Even worse would be having to scramble to create a Plan B for a beach event, then worry about health issues among attendees.' She suggests speaking with a lawyer about adding a frustration of purpose clause to the contract if the unusable condition of the beach extends beyond a certain date. 'It might help you get out of working with that particular hotel, but it still doesn't solve the issue of finding a last-minute replacement.'

Scientists say a record amount of seaweed hit the Caribbean and nearby areas in May
SAN JUAN, Puerto Rico — A record amount of sargassum piled up across the Caribbean and nearby areas in May, and more is expected this month, according to a new report. The brown prickly algae is suffocating shorelines from Puerto Rico to Guyana and beyond, disrupting tourism, killing wildlife and even releasing toxic gases that forced one school in the French Caribbean island of Martinique to temporarily close.

Caribbean beaches blighted by record masses of stinking seaweed
A record amount of sargassum has piled up across the Caribbean and nearby areas in May, and more is expected this month, according to a new study. The brown prickly algae is suffocating shorelines from Puerto Rico to Guyana and beyond, disrupting tourism, killing wildlife and even releasing toxic gases that forced one school in the French Caribbean island of Martinique to temporarily close. The amount – 38m tonnes – is the biggest quantity of algae observed across the Caribbean Sea, the western and eastern Atlantic and the Gulf of Mexico since scientists began studying the Great Atlantic Sargassum Belt in 2011, said Brian Barnes, an assistant research professor at the University of South Florida who worked on the new report from the University of South Florida's Optical Oceanography Lab. The previous record was set in June 2022 , with some 22m tonnes. 'The peaks just seem to keep getting bigger and bigger year after year,' he said. But scientists don't know why yet. 'It's the million-dollar question,' he said. 'I don't have a supremely satisfying answer.' Three different types of sargassum exist in the Caribbean and nearby areas, reproducing asexually as they remain afloat thanks to tiny air sacs. They thrive in different ways depending on sunlight, nutrients and water temperature, factors that scientists are currently studying, Barnes said. Experts have also said that agricultural runoff, warming waters and changes in wind, current and rain could have an effect. While large clumps of algae in the open ocean are what Barnes called a 'healthy, happy ecosystem' for creatures ranging from tiny shrimp to endangered sea turtles, sargassum near or on shore can wreak havoc. It can block sunlight that coral reefs need to survive, and if the algae sinks, it can smother reefs and sea grasses. Once it reaches shore, the creatures living in the algae die or are picked off by birds, Barnes said. Huge piles of stinky seaweed also are a headache for the Caribbean, where tourism often generates big money for small islands. In the popular tourist spot of Punta Cana in the Dominican Republic, officials have invested in barriers to prevent sargassum from reaching the shore. In the Dutch Caribbean territory of Sint Maarten, crews with backhoes were dispatched in late May as part of an emergency cleanup after residents complained of strong smells of ammonia and hydrogen sulfide, which can affect a person's respiratory system. 'The smell is quite terrible,' Barnes said. Meanwhile, in the French Caribbean, officials expect to soon use storage barges and an upgraded special vessel that can collect several tonnes of seaweed a day. The sargassum 'disfigures our coasts, prevents swimming and makes life impossible for local residents', the French prime minister, François Bayrou, recently told reporters. But Comito said such vessels were 'massively expensive' and not a popular option, noting that another option – using heavy equipment – is labor-intensive. 'You have to be careful because there could be sea turtle eggs affected,' he said. 'It's not like you can go in there and massively rake and scrape the whole thing.' Some Caribbean islands struggle financially, so most of the cleanup is done by hotels, with some offering guests refunds or a free shuttle to unaffected beaches. Every year, the amount of sargassum expands in late spring, peaks around summer and starts to decline in the late fall or early winter, Barnes said. The new record is likely to be broken – experts said they expect even more sargassum for June.

A mystery wave of seaweed is causing a stink in the Caribbean
A record amount of sargassum seaweed amassed across the Caribbean and surrounding areas in May, with more expected this month, according to a recent report. The brown algae is blanketing shorelines from Puerto Rico to Guyana, disrupting tourism, killing wildlife, and emitting toxic gases. One school in Martinique was temporarily closed due to the fumes. The volume of seaweed—38 million metric tons—is the largest quantity observed in the Caribbean Sea, the western and eastern Atlantic, and the Gulf of Mexico since scientists began monitoring the Great Atlantic Sargassum Belt in 2011. Brian Barnes, an assistant research professor at the University of South Florida and contributor to the report published by the university's Optical Oceanography Lab, confirmed the findings on Monday. The previous record was set in June 2022, with approximately 22 million metric tons. 'The peaks just seem to keep getting bigger and bigger year after year,' he said. But scientists don't know why yet. 'It's the million-dollar question,' he said. 'I don't have a supremely satisfying answer.'

Huge piles of stinky seaweed also are a headache for the Caribbean, where tourism often generates big money for small islands. 'It is a challenge, but it's certainly not affecting every single inch of the Caribbean,' said Frank Comito, special adviser to the Caribbean Hotel and Tourism Association. In the popular tourist spot of Punta Cana in the Dominican Republic, officials have invested in barriers to prevent sargassum from reaching the shore, he said. In the Dutch Caribbean territory of St. Maarten, crews with backhoes were dispatched in late May as part of an emergency clean-up after residents complained of strong smells of ammonia and hydrogen sulfide, which can affect a person's respiratory system.

Every year, the amount of sargassum expands in late spring, peaks around summer and starts to decline in the late fall or early winter, Barnes said. The new record set is hardly stationary — experts said they expect even more sargassum for June.
