Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
454 PM 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 will vary quite a bit due to an
ongoing land breeze and cold nearshore water temperatures. The
western flank of the ridge will lift northward into tonight and
will generally help to freshen breezes as they shift east
southeasterly. 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.
