Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
435 AM EST Wed Feb 25 2026
.SYNOPSIS...
An Atlantic ridge reaching westward across the Florida Peninsula
will pull further eastward and away from our area over the next
couple of days. As a result, breezes will gradually shift further
east and south of east. Winds today will vary quite a bit due to
an ongoing land breeze and cold nearshore water temperatures.
Winds this morning will range from northwest to north near the
mainland, and northeast to east elsewhere. The western flank of
the ridge will lift northward late today into tonight and will
generally help to freshen breezes as they shift east
southeasterly. Cautions may be required for the Florida Straits
tonight. Nearshore waters will likely remain a notch or two lower
due to still cool waters. Thereafter, winds will be light to
gentle northeast to easterly due to the general higher pressure
over the eastern United States and lower pressure to our south.
