Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
437 PM EDT Wed Aug 26 2026
.SYNOPSIS...The western periphery of an Atlantic high is expected
to maintain control of the Keys for the next several days. This
will promote peaking and lulling east to southeast breezes.
Breezes will peak in the evening through early morning hours and
lull in the afternoons. The strongest surge of breezes is
anticipated to be tonight where mostly moderate breezes are
expected throughout the Florida Keys coastal waters. In addition,
the southeasterly flow will also keep deep moisture in place
across the region with daily chances of showers and thunderstorms.
Locally hazardous winds and seas are expected in the vicinity of
thunderstorm activity.
