Tidal Information

Tidal Predictions, including along the Gulf Coast

This website http://www.tides.com/tcpred.htm has about 20 locations along the Texas coast where tides are predicted for either today or tomorrow. You will have to select the Gulf Coast as your region and then get a list of the Gulf locations that are available. Once you submit your request, a chart and a table are prepared for screen viewing. You must have graphics capabilities to use this site.
Site will allow you to set areas, time length, manner of display http://tbone.biol.sc.edu/tide/sitesel.html
Using this difference table, you can manually compute good estimates of tidal levels using Galveston bay as a starting point.

If you are interested in understanding tides better or having a more mathematical look at tidal action, this website http://math.math.sunysb.edu/~tony/tides/index.html is for you.

The National Oceanic and Atmospheric Administration website has a lot of information including how to predict tides at various locations along the coastline of the United States. Here you can order paper copies of charts and find Galveston Bay tides for four days http://www.opsd.nos.noaa.gov/
