Flamenco sits above 80° nearly year-round, and never far below it even in February. The station is in the harbor on Culebra's other side, which holds heat better than the open water off this beach.

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.

About this reading

The Culebra harbor station sits in the harbor; open-water surf can read a few degrees different.
