Marine Weather and Tide Forecast for Captiva, FL

DISCUSSION
Issued at 1220 AM EST Thu Feb 12 2026 A weak frontal boundary will sink south across the Florida peninsula today with a slight chance of showers. The front will stall over south Florida tonight and will gradually dissipate on Friday. High pressure along the mid Atlantic coast will build over the forecast area in the wake of the front. Little change in the overall airmass, however dew points will drop a bit across the nature coast. This will maintain favorable conditions for late night/early morning fog across west central and southwest Florida into the weekend, which may be locally dense.
Temperatures will also run above climatic normals each day through the weekend. Onshore boundary layer flow today will shift to the north/northeast Thursday night and Friday behind the front...then to the east Friday night...and to the south/southeast on Saturday as the center of high pressure moves off the mid Atlantic coast.

A southern stream disturbance will move across the southeast U.S.
and Florida peninsula Sunday and Monday with numerous to widespread showers and a slight chance of thunderstorms pushing across the forecast area. High pressure will build back over the region in the wake of this system with slightly cooler drier air moving over the area...but temperatures will run near climatic normals...with a gradual warm up mid week.
