Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
448 PM EDT Sat Jun 13 2026
Florida Bay, Hawk Channel and Straits of Florida from Ocean Reef
to south of Dry Tortugas, and the extreme southeastern Gulf of
America, including The Florida Keys National Marine Sanctuary
Seas are given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.
Wave Detail will include details about the period and direction
of origin for the highest energy waves. Long-period swells coming
from a different direction than the wind would be included in the
Wave Detail.

Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
448 PM EDT Sat Jun 13 2026
.SYNOPSIS...Light to gentle east to southeasterly breezes will
persist across the Florida Keys this afternoon. The combination
of a well-developed mid-latitude trough over the eastern United
States and a weak disturbance over the Bay of Campeche weakened
the ridge over the Caribbean Sea. Breezes are on track to veer
southeast to south late in the weekend and early next week.
