Sargassum Seaweed Plagues Florida and Caribbean Beaches
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. Onshore winds exacerbate the issue, causing the seaweed to pile up on beaches, rot, and emit a foul odor. This year, the phenomenon is particularly severe, with NOAA's Daily Sargassum Inundation Risk tool showing high-risk areas across southern Florida, including Miami, Fort Lauderdale, and Palm Beach County, as well as popular Caribbean destinations like the Dominican Republic, Puerto Rico, Barbados, and Jamaica. However, not all beaches are affected equally, as leeward sides of islands tend to experience less accumulation.
