Expires:202512141730;;547782 FZUS54 KHGX 140456 CWFHGX Coastal Waters Forecast for Texas National Weather Service Houston/Galveston TX 1056 PM CST Sat Dec 13 2025 Upper Texas coastal waters from High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays. Seas are provided as a range of the average height of the highest 1/3 of the waves...along with the occasional height of the average highest 10 percent of the waves. GMZ300-141730- 1056 PM CST Sat Dec 13 2025 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays. In the remaining hours before the front arrives, expect light onshore winds, low seas, and even patchy fog redevelopment. The front is about to move into the Houston metro, and should be pushing into the bays after midnight, and out over the Gulf between 3 and 6 am. While light winds and any fog may linger for a short while after the front passes, they will scour out shortly afterwards as strong, gusty north to northeast winds build in the front's wake. Along with the strong winds, building seas will follow. Gusts to near gale force are expected on the bays, and frequent gusts to or above gale are likely on the Gulf. A Small Craft Advisory is in place for the Bays and a Gale Warning on the Gulf until late Sunday night. For those working onshore, a wind advisory is in place on all islands and peninsulas beyond the Intracoastal Waterway as well as Chambers County on Sunday. Winds and seas gradually diminish Monday morning, and return to a southeast direction by Monday night. The quick turn in winds should prevent low tides from getting low enough to require a Low Water Advisory, but we should still see a few low tide cycles with levels around or slightly below MLLW. $$ |
