Surfside, Tx is my favorite place to sup surf on the upper Texas coast with regards to wind and wave conditions. Our waves are wind generated. We don't have a large drop off in depth from the beach out. Think of a dinner plate so far from the beach, the water is still shallow.
With much wind, we have tiny waves which one can see in another topic thread. With some wind and combined that with our normal prevailing onshore wind direction (southeast or south), depending on the wind speed we get some good moderate waves which you can see in the video below which was taken close to Drum Point. If you notice, most of the women were surfing longboards and they had better rides than some of the men who were surfing shortboards. At these times, I'm never along, but I'm usually the only one sup surfing on a sup.
As the wind speed picks up to 20 mph or more, we get "washing machine type of waves with plenty of whitewater" which you can see in the next video below. Notice the flag in the breeze which is sticking straight out. Never mind the audio of the people speaking. The point of this video is to show the waves which I find when I get down the beach at Drum Point. And just listen to the wind whipping.
Since I've got more info, I'm going to make another post since I don't know how many videos I can put into one post.
