Frequently Asked Questions
- What conditions does Big Buoy track near Galveston Bay?
- Big Buoy provides real-time water temperature, wave height, wind speed and direction, swell period, and atmospheric pressure from NOAA stations across the region, including Galveston, Freeport, and SSE of Corpus Christi. You also get 7-day tide forecasts, solunar tables, and extended weather outlooks for the upper Texas coast and Galveston Bay system.
- How do tides work at Galveston?
- Tidal range along the upper Texas coast is small — rarely exceeding 2 feet — but wind-driven tides can push water in and out of the back bays dramatically, sometimes exceeding the astronomical tide by several feet. The wind forecast matters as much as the tide chart on this stretch of coast. Southerly winds pile water into the bay; northers push it out.
- What conditions should I check before heading out at Galveston?
- Wind direction and speed are the most important variables at Galveston — they control water levels in the back bays more than the astronomical tide does. Check the wind forecast first: southerly winds push water in and raise levels, while northers drain the bays. Water temperature in the shallow bays can exceed 85°F in summer, and rapid cooling during fall cold fronts triggers dramatic condition changes. After heavy rain, check for freshwater runoff from the Trinity River which affects water clarity throughout the system. Big Buoy shows real-time Gulf buoy data plus tide and weather forecasts for planning.
