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

Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
426 AM EST Fri Dec 26 2025
.SYNOPSIS...High pressure centered over the northeastern Gulf will
support gentle to moderate mainly north to northeast breezes this
morning. The high will weaken as it drifts slowly southeastward
through the weekend, leading to slackening breezes. A potent cold
front is expected to move through the Keys towards the middle part
of next week. This will lead to freshening northerly breezes
throughout all the Florida Keys coastal waters.
