Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
432 PM EDT Wed Jul 15 2026
.SYNOPSIS...
Elongated high pressure across the Florida Peninsula will support
gentle to moderate east to southeast breezes through the rest of
the week for the Keys coastal waters. Breezes will tend to peak in
the evening and overnight hours, before modestly lulling in the
late morning and afternoon periods. A large area of Saharan dust
will remain in place across the Florida Keys marine zones for the
next several days, acting to limit rain and thunder chances.
