Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1025 PM EDT Sat Aug 1 2026
.SYNOPSIS...
Light and variable winds will initially persist through the first
half of the overnight period. As high pressure begins to
strengthen in the North Atlantic, breezes will freshen while
becoming southeast late tonight. Light to gentle breezes will
continue into early next week with some occasional periods of
gentle to moderate. In addition, rain chances will also be
increasing by next week as deeper moisture spreads into the region
ahead of a frontal boundary approaching northern Florida. As
chances for showers and thunderstorms increase next week, mariners
can expect higher winds and seas near this activity.
