Coastal Waters Forecast for Texas
National Weather Service Houston/Galveston TX
For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays.
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. High pressure over the western Gulf continues to bring light to moderate west-southwest breezes over the waters with seas around 2 to 3 feet. This should continue through Wednesday before influence from Tropical Storm Bertha potentially begins. There remains high uncertainty in the forecast track and intensity of Bertha, though the official forecast calls for weakening back to a depression late in the week. Given this, significant impacts in our waters is not expected, but some impact to small craft is possible if higher winds and seas materialize, mainly offshore.
