Marine Weather and Tide Forecast for Gulfport, FL

DISCUSSION
Issued at 126 PM EST Thu Feb 12 2026 Northwest flow continues aloft this afternoon with high pressure centered over Mexico. At the surface, a weak frontal boundary is slowly moving southward over the peninsula, with just a few light showers accompanying it. This boundary will gradually dissipate on Friday, then high pressure builds over the southeast and holds over the region as it shifts eastward through the weekend. Overall, our local weather will not change much over the next several days, with generally mild conditions and fog being the primary concern each night.

Late this weekend into early next week, a disturbance will move along the northern Gulf coast, eventually bringing our next (and good) chance for rain and maybe even a few thunderstorms. The best rain chances at this time look to be late Sunday through early Monday morning, clearing by Monday night. High pressure then builds back in for the rest of the week, with near to slightly above normal temperatures expected.

AVIATION
(18Z TAFS)
Issued at 126 PM EST Thu Feb 12 2026 VFR conditions are expected through the rest of the day, then fog and low clouds are expected again tonight with IFR conditions or worse, then clearing by mid morning.

A front will push through Sunday and Monday, with showers and a few storms, followed by increasing winds near headlines. High pressure then builds back over the region through mid week.

FIRE WEATHER
Issued at 126 PM EST Thu Feb 12 2026 Relative humidity values will remain above critical levels with no Red Flag concerns. The main issue will be fog tonight into tomorrow morning, mainly from around Tampa Bay southward.
