It is difficult timing your schedule with when the surf is calm and green so I would suggest focusing on bay fishing and then possibly hitting the surf. Either place, fishing dead or live shrimp under a popping cork is the best way to ensure you catch at least something. A good multi species lure is a silver or gold spoon.
Freshwater: most bayous and lakes in community parks around the Houston area have bass, sunfish, catfish and possibly other catchable fish (e.g. crappie, tilapia). There are countless possibilities that you can find using a little research on google maps and the internet. Just as an example, tHere is a good website on fishing in the Woodlands which is a northern suburban area of Houston (fishinginthewoodlands.com).
Good luck and let us know how you did!!
