Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1020 PM EST Wed Jan 7 2026
.SYNOPSIS...A ridge axis extending from the Central Atlantic and
across the Gulf Basin will become reinforced by another ridge
shifting in from the west, allowing breezes to freshen to gentle
to moderate through the end of the week and become more easterly.
The exception will be out across the Straits of Florida, where
moderate to occasionally fresh breezes will be possible. The next
cold front passage is looking to be late Sunday into early Monday
with freshening northerly breezes in the wake.
