Sargassum Chokes Mexico’s Caribbean Coast

A record influx of sargassum is covering beaches across Mexico’s Caribbean coast and neighbouring islands, threatening the region’s tourism economy. Quintana Roo expects about 119,000 tonnes during 2026, exceeding last year’s record. When the seaweed decomposes, it creates strong odours, affects water quality and can expose workers and visitors to harmful gases. Beach closures and weaker sales are already hurting hotels, restaurants and excursion providers. Resorts must communicate beach conditions honestly, strengthen offshore collection and offer alternative experiences. For tour operators, flexible itineraries and property-level monitoring are essential because conditions can differ significantly between beaches, islands and individual travel dates.
