422 AM EST Fri Jan 2 2026
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 EST Fri Jan 2 2026
.SYNOPSIS...High pressure over the central Gulf will maintain
light to gentle north to northeast breezes this morning. As the
high moves overhead this afternoon, breezes will become light and
variable. A weak front is expected to pass through the Key late
Sunday/Sunday evening with a return of northerly breezes. In the
wake of the front, high pressure will slide across the eastern
United States. This will maintain northeast breezes initially
before becoming mainly easterly as the high moves out into the
Atlantic.
