Does Jamaica Get Sargassum?

Jamaica

Sargassum in Jamaica by month

What to know before you book

• •Jamaica's national environment agency (NEPA) names Portland, St Thomas, St Catherine and Westmoreland as the parishes that bear the brunt of influxes - that is the east end, the south coast around Hellshire, and stretches of the far southwest, not the Montego Bay/Ocho Rios tourist corridor.
• •Negril's Seven Mile Beach faces west into the sheltered Caribbean and is the least sargassum-prone major resort beach on the island; Tripadvisor regulars consistently report it as a non-issue, though not perfectly consistent.
• •Jamaica runs a three-tier National Sargassum Response Strategy: hotel and beach operators handle daily raking, parish councils and the national waste authority handle larger events. NEPA prohibits tractors and front-end loaders without a permit, so removal is mostly hand and belt-raking and cleanup is slower than in the Dominican Republic.
• •The Jamaica Sargassum Early Advisory System (JSEAS) issues local warnings using USF satellite data - worth checking if you are booked on the south or east coast in summer.
• •2026 was the second-largest sargassum year on satellite record behind 2025; the Caribbean Sea region peaked in June and USF measured declines through July and August with further decline expected into November.
