444 PM EDT Thu Apr 24 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
444 PM EDT Thu Apr 24 2025
.SYNOPSIS...High pressure off the Mid-Atlantic will support
freshening easterly breezes peaking overnight. As the high slowly
slides eastward in the west-central North Atlantic, breezes will
modestly slacken for Friday afternoon through the weekend,
becoming moderate to occasionally fresh. A second area of high
pressure will push eastward from the Mid-Atlantic into the western
North Atlantic for early next week, helping to reinforce the
stagnant, mainly dry synoptic pattern.
The Approximate Shoreward Edge of the Gulf Stream as of April
22nd...
30 NM South of Dry Tortugas Light...on Loggerhead Key.
6 NM South of Cosgrove Shoal Light...off the Marquesas Keys.
