What to Know About Sargassum Seaweed in Mexico

By Adam Leposa Sep 2, 2019 8:00am

Sargassum seaweed has been drawing a great deal of attention in the consumer media, as many tourist destinations in Mexico and the Caribbean have suffered unsightly drifts of the plant on their beaches. YesToMexico, an organization dedicated to providing accurate Mexico travel information, has released a guide to the seaweed to educate travelers on the situation.

Sargassum 101

Sargassum is a traditionally periodic occurrence that makes itself known on Mexico’s Caribbean Coast from April to October.
The severity and timing of sargassum is influenced by the tides and can vary day-to-day, and destination-by-destination.
All of Mexico is not impacted by sargassum. The Pacific Coast is sargassum-free, and in parts of Mexico’s Caribbean Coast, the impact varies. For example, the resorts of Cozumel and Isla Mujeres have shown small to virtually no signs of sargassum this year.

Know Before You Go

While sargassum patterns are influenced by unpredictable natural forces, that doesn’t mean travelers cannot investigate its impact before they travel.
Be a Sargassum Spy: Many resort brands, including Krystal Hotel & Resorts, and Beachscape Kin Ha Villas & Suites Cancun, offer their guests 24/7 beach cams that show a live look at their beautiful beaches. This way travelers can see what the beach is like at their favorite time of day prior to booking or travel.

Keeping Sargassum at Arm’s Length

Some resorts have installed barrier systems to help keep sargassum off their beaches or invested in a maritime fleet to help with pick-up at sea. Examples include:

In Puerto Morelos, Zoëtry Paraiso de la Bonita invested in a $120,000 industrial seaweed barrier for its 1,900-foot stretch of beach, while Desire Riviera Maya Resort spent more than $96,000 to create a 918-foot-long linear barrier. Combined these barriers helped collect more than a ton of seaweed each day.
Bahia Principe Hotels & Resorts launched an eco-friendly response plan that includes a network of boats to contain and redirect sargassum, while safely collecting the algae. The early results show a 95 percent reduction in sargassum at the company's resorts.

Now You See It, Now You Don’t

If sargassum does reach beaches, resorts have implemented extensive clean-up efforts. Manual beach pickup is taking place at some hotels and resorts two to three times per day to ensure their beaches are sargassum-free, while other resorts, such as the Royalton Suites Cancun Resort & Spa, Ritz-Carlton Cancun, JW Marriott Cancun Resort & Spa and Marriott Cancun Resort, are leveraging special equipment to assist with quick pick-up. Hotel Xcaret México takes the pick-up efforts even a step further, using an aerial monitoring system to watch overnight accumulation of sargassum, and then at dawn staff complete collection, taking the sargassum to Grupo Xcaret’s processing facility.

Planning for the Future

In July, Cancun hosted a tourism industry summit in which leaders from 13 impacted countries attended to discuss short and long-term solutions to address Sargassum including research and warning systems. In addition, government entities have also come together to help popular tourist destinations. In Tulum, the “Cleaner Beaches Program”, in collaboration with the federal, state and municipal government, have removed and disposed almost 2,000 tons of Sargassum.

Putting Sargassum to Good Use

While much is focused on sargassum collection, disposal is also important. The Sargasso Industrial Association, a collective of five private sector companies, is turning it into biofertilizer for food crops.

In addition, one local is using the sargassum in an even more unexpected way. Omar Vazquez is building sustainable homes with “sargablocks,” which are created from collected sargassum.
