NWS Marine Forecast


   GMZ300-122330-  Synopsis for High Island to the Matagorda Ship Channel out  60 nautical miles including Galveston and Matagorda Bays  532 AM CDT Thu Jun 12 2025    .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM  including Galveston and Matagorda Bays.    Mariners should be aware of ongoing storms over the bays and very  near the Gulf waters. Though more broadly speaking, winds of 10-15  knots with gusts to around 25 knots, localized conditions in and  near stronger storms may be much worse. In and near the stronger  storms, one can expect wind gusts to gale force, reduced  visibility in rain, and higher chaotic seas. Storms are already  occurring over the bays, and will be likely in the Gulf waters  very near shore. Farther offshore, the potential for storms will  diminish. After today's storms move out, look for a brief respite  late this evening, but a new round of storms will move in from the  west late tonight, and expectations for storms will exist again  for the bays and nearshore Gulf waters Friday. Outside of any  rain, onshore winds will prevail with seas generally in the 3 to 6  foot range.    $$
