Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1028 AM EDT Fri Jul 25 2025

.SYNOPSIS...Atlantic ridging is expected to dominate the forecast
for the next several days. The surface ridge will be at its
strongest today before starting to weaken and sliding off to the
west heading through the weekend. This will promote moderate to
fresh east to southeast breezes through tonight with slackening
thereafter. The exception will be the western Straits of Florida
where the breezes may linger into Saturday night. For the second
half of the weekend and into early next week, weak Atlantic
ridging will remain in place promoting light to gentle breezes.
