Marine Weather and Tide Forecast for Gibsonton, FL

DISCUSSION
Issued at 355 AM EDT Tue Aug 4 2026

The upper level troughing over the eastern U.S. will gradually weaken over the next few days with ridging trying to build west from the Atlantic Ocean. This will allow the surface ridge that has been anchored south of the region to drift north across the area during midweek and then setup to our north late in the week through the weekend.

Today will be the last day of the southwest to west flow. More scattered to numerous showers and thunderstorms will move east across the area with locally heavy rainfall possible, especially around the Tampa Bay area this morning where the band of deepest moisture resides.

Tonight into Wednesday will be the transition period as the surface ridge sets up across the region. Deep moisture will remain across the area and with the light flow we'll likely see some scattered late night and morning convection over the gulf waters affecting coastal areas, then more scattered to numerous showers and thunderstorms developing over land during the afternoon drifting west back toward the west coast.

For Thursday through early next week, an east to southeast flow will become established. Plenty of moisture will be across the area and this combined with daytime heating and the sea breezes will lead to scattered to numerous mainly afternoon and evening convection each day.

Daytime highs will remain near to a few degrees below normal today. Then as the east to southeast flow returns we'll see daytime highs climb back to near to a few degrees above normal with overnight lows near normal.
