Houston–Galveston, Texas – A Low Water Advisory remains in effect across the upper Texas coast through at least Wednesday evening, as persistent offshore winds continue to push water out of area bays and waterways.
According to the National Weather Service Houston–Galveston, each low tide cycle through Wednesday could drop water levels to around 1.5 feet below Mean Lower Low Water, especially across Galveston Bay and Matagorda Bay. The most severe impacts are expected in the upper portions of the bays, where shallow channels and restricted access points are more common.
These unusually low water levels significantly increase the risk of vessel grounding, particularly for recreational boaters, commercial operators, and anyone navigating unfamiliar waters. Mariners are urged to closely monitor water depths, adjust routes as needed, and allow extra clearance when transiting channels.
Communities around Houston, Galveston, Texas City, League City, Baytown, Freeport, and Port O’Connor may notice exposed shorelines, stranded docks, and limited access at boat ramps. Travel corridors near coastal infrastructure, including Interstate 45, Interstate 10, State Highway 146, Highway 288, and FM 518, may see increased marine and industrial activity adjustments due to the low water conditions.
In addition to the marine impacts, cold overnight temperatures have added to the challenges for early-morning commuters and outdoor workers. While temperatures are expected to gradually warm through Thursday, another cold front is forecast to arrive late in the week, potentially reinforcing chilly conditions.
The National Weather Service advises boaters to reduce speed, follow posted depth markers, and remain alert during low tide periods. Those with plans on the bays should remain cautious until water levels return closer to normal later this week.
Residents are encouraged to stay informed by checking updated marine forecasts and advisories as conditions evolve along the upper Texas coast.
