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
438 PM EDT Fri May 16 2025
.SYNOPSIS...A dry pattern defined by a distant high pressure
system in the central Atlantic and lack of a close high over the
CONUS will lead to breezes shifting from light to moderate breezes
for the next few days. In the absence of nearby strong pressure
systems, breezes will peak and lull through Tuesday. Near nil
shower chances will persist until Wednesday as an increase in
moisture allows for possible showers and isolated thunderstorms.

10th...

8 NM South of Cosgrove Shoal Light...off the Marquesas Keys.
