Seaweed season

On the Caribbean, sargassum season runs from April through August, heaviest from June through July.

The bulletins cover the Caribbean Sea as a whole rather than island by island, and put the basin's heaviest months in summer — so read this as the region's shape, not this beach's.

  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.
