Coastal Waters Forecast for the Florida Keys
National Weather Service Key West FL
432 AM EDT Tue May 13 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
432 AM EDT Tue May 13 2025
.SYNOPSIS...
Moderate south to southwest breezes will veer more westerly while
the heart of the parent low meanders along the northern Gulf.
Scattered showers with embedded isolated thunderstorms will
continue this morning diminishing in coverage and frequency as the
day progresses. As the low lifts toward the northeast during the
middle of the week, higher pressure will be able to fill in behind
it, encouraging drier weather and slackening breezes.
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.
