Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
419 AM EST Sat Nov 8 2025
.SYNOPSIS...High pressure will continue to slide eastward across
the central North Atlantic today and Sunday. This will result in
mainly light east to southeast breezes, potentially becoming
variable at times. A potent cold front will push through the
Florida Keys marine zones on Monday with fresh to strong
northerlies expected in its wake early next week. While the next
high builds in behind the front, winds will shift out of the
northeast and gradually slacken. Moderate to occasionally fresh
breezes will remain possible.
