Miami-Dade crews hauled a record 9,000 tons of sargassum off local beaches in July, an extraordinary amount of seaweed that has left cleanup crews scrambling and some longtime beachgoers wondering what they will find when they reach the water.
The July total was the most sargassum Miami-Dade has ever removed in a single month, according to The Guardian’s Aug. 18 report. For beachgoers, conditions can change dramatically depending on the day and stretch of shoreline.
One person commenting in a recent r/Miami discussion about beach conditions said they had lived in the area for decades and described finding a clear beach as “a complete crapshoot.” Other commenters in the same discussion offered a much less dire picture, reporting little or no seaweed around some sections of South Beach on particular days. That split reaction highlights one of the headaches for residents and tourists: a beach that looks rough one day may look significantly better the next.
Crews Can Clean a Miami Beach — and Watch the Seaweed Return
Chris Bumpus, chief of conservation for Miami-Dade County’s Parks, Recreation and Open Spaces Department, told The Guardian that his crews maintain about 17 miles of county beaches.
During the worst stretch in July, Bumpus said a freshly cleaned beach could stay that way for only about an hour before more sargassum arrived. Miami-Dade’s official sargassum information page says county crews conduct daily maintenance from Government Cut north to the Broward County line, as well as at Crandon Park. Specialized equipment is also used at several designated hot spots, including sections of Miami Beach and areas near Haulover Cut.
The county says about $3.9 million a year is specifically allocated for sargassum removal as part of a larger beach-maintenance budget. Cleanup is not as simple as scooping everything out of the ocean.
Floating sargassum provides habitat and food for marine animals, and state and federal environmental rules restrict wholesale removal from the water. Sea turtle nesting season also overlaps with sargassum season, requiring crews to survey and protect nests before heavy machinery is used on beaches.
2026 is Still One of the Biggest Sargassum Years on Record
There is at least some indication that the peak may have passed. University of South Florida researchers now expect 2026 to finish as the second-highest sargassum year on record, rather than surpassing 2025. Brian Barnes, lead scientist for USF’s Sargassum Watch System, said overall amounts began declining in July, although significant beaching events continued along Florida’s southeast coast. WUSF reported on the updated outlook Aug. 13.
That is cold comfort for beachgoers, however, who have already encountered thick mats of brown seaweed this summer. In the r/Miami discussion, one regular runner described conditions as extremely heavy, while another local said the problem was being exaggerated and that visitors should not cancel their trips because individual stretches of beach can remain clear.
That variability is why several commenters recommended checking Miami Beach webcams immediately before heading out rather than relying on what the shoreline looked like a day or even a few hours earlier.
Miami-Dade says the heavier seasonal conditions typically improve around October or November, but officials also warn that the Great Atlantic Sargassum Belt could make seaweed an increasingly regular part of South Florida summers.
For now, Miami’s cleanup crews are fighting the problem one stretch of sand at a time — and after a record 9,000-ton month, beachgoers may want to check the cameras before packing the cooler.
