Marine Weather and Tide Forecast for Galveston, TX

DISCUSSION
Issued at 1228 PM CST Wed Mar 4 2026

With some peaks of sun emerging and warming temperatures, we're beginning to see a few returns show up on radar. Would anticipate some continued iso-sct shra/tstm development in the next 2-4 hours with continued daytime destabilization. That said, the vast majority of us won't see much in the way of measurable precip.
Otherwise, unseasonably warm wx continues with daytime highs in the 80s and overnight lows in the upper 60s-low 70s to round out the work week.

Mid-upper trof over the Pacific Northwest will dig sewd and over the Rockies by Friday. The northern part of the trof will then lift to the ne this weekend and its trailing surface front will sag into the region Saturday. The southern portion of the mid- upper trof will cutoff and retrograde swly off the Baja coast.

Deeper Gulf moisture will be pooling along and south of our weekend surface front which should be stalling in the region as it loses its southward momentum. These higher PW's, in combination with daytime heating, favorable upper jet positioning, and a series of impulses moving across in the swly flow aloft should provide pretty good chances of shra/tstms across the area Sat & Sun.

Our cutoff low off Baja will kick out early next week and track across Texas in the Tue-Wed timeframe and bring us another shot of shra/tstms. 47

AVIATION
(00Z TAF Issuance)
Issued at 549 PM CST Wed Mar 4 2026

Showers (plus one lonely CG strike 15ish SM west of UTS) are close enough to have a short VCSH mention in the UTS TAF before rain winds down this evening, but dry everywhere else. Beyond that, GLS is already at 1/4SM with sea fog, so the TAFs are largely a slightly faster version of persistence, with conditions degrading to low MVFR far north to LIFR at the coastal terminals.
Expect gradual return to VFR for the afternoon along with return of breezy south/southeast winds.

MARINE
Issued at 1228 PM CST Wed Mar 4 2026

A long fetch of southeast winds will persist over the coastal waters through the weekend along with slowly building seas.
Warmer air moving over the cooler shelf waters near and off the Galveston coast will be favorable for periods of haze and fog
moreso in the Gulf waters
though it could intermittently move into southern Galveston Bay during the overnight and early morning hours. One limiting factor in terms of visibilities might be slightly higher wind speeds that may mix the atmos enough to keep the widespread dense variety in check. Rain chances increase this weekend, though at the current time, it appears the best chances will be inland near a stalled frontal boundary. 47
