Seaweed season

On Florida's southeast coast and the Keys, sargassum season runs from April through August, heaviest from June through July.

USF's bulletins treat the Keys and the southeast coast together, and in an ordinary year report them largely clear until late April or May. North of Cape Canaveral the bulletins say nothing either way, so neither do we.

  1. January: rare
  2. February: rare
  3. March: rare
  4. April: some seaweed
  5. May: some seaweed
  6. June: peak season
  7. July: peak season
  8. August: some seaweed
  9. September: rare
  10. October: rare
  11. November: rare
  12. December: rare

This is a pattern, not a forecast. The lab that watches this says plainly that predicting seaweed on an individual beach is difficult or impossible — whether it comes ashore depends on winds, tides and currents nobody can call ahead. The bulletins track how much is out there and look about a month on.
