Marine Weather and Tide Forecast for Galveston, TX

LONG TERM
(Wednesday through next Sunday)
Issued at 1154 PM CDT Sun May 11 2025

Mid to upper level ridge will dominate the local weather pattern through at least the end of the work week and will limit the development of showers over SE TX. Although conditions will be tranquil, expect summerlike temperatures mid-week as S-SE surface winds and a W-SW low level jet increase our local temperatures.
We could be looking at high temperatures reaching 100 deg F over portions of the Brazos Valley and Piney Woods region on Wednesday, while the rest of the inland portions reach the mid to upper 90s and the upper 80s to lower 90s over the immediate coast.

For the rest of the week, we can expect the highs to remain in the mid to upper 90s over areas north of I-10, the low to mid 90s over areas along and south of I-10, and the upper 80s to lower 90s over the coasts. As stated in the previous discussion, the Heat Indices will be in the lower 100s for most days, and even if this range does not hit the Heat Advisory Criteria, it is recommended to take the necessary precautions if you plant to work or spend time outside given that we are not yet acclimated to these temperatures. Take additional breaks and limit sun exposure, drink plenty of water, and stay in the shade if possible. Be aware of the symptoms of heat exhaustion.

With respect to the nighttime/early morning temperatures, the low temperatures will also increase, going from the low to mid 70s on Wednesday night to the mid to upper 70s by the end of the work week.

Our next best chance for rain may occur during the weekend as a few upper level shortwaves through TX. The bad news is that much of this activity is mainly focused over the NE counties (in and around Houston County).

MARINE
Issued at 1154 PM CDT Sun May 11 2025

Light to occasionally moderate offshore winds and seas of 3 feet or less is expected to prevail through Monday morning. Onshore flow should return late Monday and strengthen mid-week as the local pressure gradient tightens. Caution flags and Advisories will be needed. The stronger winds will lead to a rise in seas, the risk for strong rip currents along the beaches, and slightly higher water levels. Winds will relax back to the light to occasionally moderate range near the end of the work week and into the upcoming weekend.
