What should be one of the world’s most famous stretches of white sand is being covered by enormous amounts of sargassum seaweed.
From the air, the contrast is striking. Bright turquoise water gives way to long, dark brown bands stretching along the shoreline. In some areas, the seaweed piles up into thick mats that blanket the beach and release a strong odor as they decompose.
The surprising part is that this isn’t pollution.
Sargassum is a floating brown algae that naturally lives in the Atlantic Ocean. While it’s an important habitat for fish, sea turtles, and other marine life offshore, massive blooms can become a major problem when ocean currents and winds push it onto beaches. Excessive amounts have affected South Florida and the Caribbean for years, but scientists say 2026 is shaping up to be one of the biggest sargassum years ever recorded. Miami Beach has already experienced significant accumulations, with cleanup crews working daily to remove seaweed from the shoreline.
Researchers monitoring the Atlantic Sargassum Belt say the amount of seaweed could continue increasing through the summer, with South Florida remaining one of the areas most at risk for major beaching events.
A beach famous for crystal-clear water is being transformed by one of the largest natural algae events on Earth.
Would you still visit Miami Beach right now?
