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/
