Record-breaking amounts of sargassum seaweed could be coming to South Florida, experts say Dr. Chuanmin Hu, a professor of Oceanography at the University of South Florida, delivered the warning following the school's latest 2026 sargassum outlook.

Drastic seaweed growth threatens marine life and fishing – but also offers opportunities Floating seaweed can travel long distances to new territories and accumulate in large mats or wash ashore in huge quantities.

"Like something from a sci-fi movie, I’ve seen swathes of #sargassum #seaweed spreading across the tropical Atlantic, with mats reaching depths of 7 metres and spanning hundreds of square miles."

PML's Dr Fidai on how blooms of seaweed are increasing globally: theconversation.com/drastic-seaw...

USF-led study reveals dramatic decline in some historic sargassum populations Even as record sargassum reaches Caribbean and Gulf shores, the Sargasso Sea — once a stable stronghold — has seen a sharp drop in healthy mats since 2015. Because sargassum mats support turtles, fish, seabirds and other marine life, a long-term drop in healthy sargassum could reshape food webs and alter the ecological balance across the broader Atlantic region.

Late Season Sargassum Returns to Cancún Beaches - The Adept Traveler A surprise late season sargassum arrival has reached Cancún beaches after November cold fronts. Crews are clearing key hotel zone stretches, and travelers should plan around daily cleanup windows.

Late season sargassum returned to parts of Cancún. Crews clear at dawn, so aim for mid to late morning swims, or pivot to Isla Mujeres or cenotes. #Cancun #Sargassum

North–south depth profile of excess P in the Atlantic. Excess P (expressed as P* = PO43−-NO3−/16 in µM) against water depth in a north–to–south transect along the western margin of the Atlantic Ocean (adapted after Deutsch et al. 2007). Positive P* values indicate excess P and are plotted in relation to P concentrations (in µmol L−1, shown as iso–concentration lines). Coral core locations are shown on top with respect to their latitude (CR = Costa Rica; TB = Little Tobago; BZ = Belize; CU = Cuba; BD = Bermuda; MQ; Martinique; MX = Puerto Morelos. SACW – South Atlantic Central Water, NACW – North Atlantic Central Water, AAIW – Antarctic Intermediate Water, NADW – North Atlantic Deep Water, AABW – Antarctic Bottom Water.
