Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
422 AM EDT Wed Apr 30 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
422 AM EDT Wed Apr 30 2025
.SYNOPSIS...
Moderate to fresh breezes will continue as high pressure
dominates the region. The high will remain fairly stagnant in
place through the middle of the week, so breezes will oscillate
between moderate to fresh on a weak diurnal trend with stronger
breezes in the evening hours. Occasional pushes of moisture
throughout the week will allow for some isolated shower activity.

22nd...
