Scroll down for the surf report.
Mostly I just use the National Weather Service Marine Forecast. You can click on a number of buoys out in the Gulf.
Leaving CA in search of waves and going to TX? Sorry to say you got it backwards. Leaving the Great Lakes and coming to TX for waves makes sense. If real waves are really what you are after, TX just won't do it for you, CA is way better. The Gulf of Mexico is just not a large enough body of water for long period ground swell.
Most traveling kiters come here because it is a great place to learn. The flats are fun and safe. The Gulf is fun with small windswell thats mostly like chop. Even hurricane swell is usually un-ridable due to the wrong wind or a complete closeout.
Sorry to rain on your trip, I just don't want you to have unrealistic expectations for waves. Otherwise, come on down!
