Why some beaches stay clean
Sargassum arrives on east-flowing Atlantic currents and piles up on east-facing, unprotected shorelines (Macao, parts of Bávaro). Reef-protected coves like Juanillo and south-facing beaches like Saona's Canto de la Playa break up the rafts before they land. Catalina sits on a different current entirely and stays clean.
