Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
422 AM EDT Fri May 16 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 Fri May 16 2025
.SYNOPSIS...A large, expansive high pressure parked in the
central North Atlantic will dominate the synoptic pattern for the
next several days across the Keys coastal waters. This will result
in minor peaks and lulls through the next several days along with
near- nil shower chances. The high will begin gradually shifting
eastward by Tuesday, allowing for an increase in moisture and a
threat for showers and possible isolated thunderstorms.
The Approximate Shoreward Edge of the Gulf Stream as of May
10th...
22 NM South of Dry Tortugas Light...on Loggerhead Key.
8 NM South of Cosgrove Shoal Light...off the Marquesas Keys.
6 NM South of Sand Key Light...off Key West.
