Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1031 PM EDT Wed Jul 29 2026
.SYNOPSIS...The western periphery of an Atlantic surface ridge
will continue to slide westward across the Florida Keys coastal
waters. This will result in a weak nebulous flow overnight through
Thursday night with slackening breezes. A col region will set up
for late week into the first part of the weekend, resulting in a
potential period of light and variable breezes. As high pressure
strengthens in the North Atlantic, southeast breezes will freshen
by the second half of the weekend and into early next week.
