Sargassum seaweed, a naturally occurring brown algae, is disrupting beachgoers across Florida and the Caribbean this summer.
According to NOAA, sargassum originates near the Amazon River and is carried by the Gulf Stream to the Atlantic Coast and Caribbean islands.

Impact & Risks

The accumulation of sargassum seaweed poses significant challenges for beachgoers and local businesses. The rotting seaweed emits a strong odor, making affected beaches less appealing for visitors. Popular tourist destinations in Florida and the Caribbean are experiencing disruptions, with images of bulldozers clearing masses of seaweed making headlines. The phenomenon also impacts marine ecosystems, as sargassum provides habitat for various species. However, its excessive presence can disrupt local economies reliant on tourism. NOAA and experts like Dr. Stephen Leatherman emphasize the unpredictability of sargassum's impact, urging travelers to check conditions before planning trips.
