Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
419 PM EDT Tue Jul 14 2026
.SYNOPSIS...
Elongated high pressure extending from the central North Atlantic
westward to the Florida Peninsula will support 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.
