Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
1019 AM EDT Tue Apr 15 2025
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
1019 AM EDT Tue Apr 15 2025
.SYNOPSIS...High pressure is still stretched across the region,
allowing for breezes to become light and variable. The decaying
tail end of a cold front will clip the local waters Wednesday, but
the only change in weather conditions will be breezes assuming a
northerly direction. On Thursday, high pressure rebuilding will
cause breezes to turn easterly and freshen quickly. Fresh to
strong breezes are expected to be in place as early as Thursday
night, and these conditions will continue into the start of the
weekend.
