Hey, that's great. You'll like it here. There's so many things to do, so many great restaurants, a lake, trails, the capitol building, and the longhorns (Hook 'em!). Anyway, most of April, May, October, and all of June, July, August, and September you have to run the a/c. For spring-fall, the average high is 85. But it gets down into the 70s during the night even during the middle of summer. There are always ways to beat the heat (There are a ton of pools). It is humid in every season except winter, making it feel hotter than it actully is. But the humidity is not as high as most of the South. It can get above 110, but that has only happened a few times. During the so-called winter, it gets into the 60s on average and drops to the upper 40s. It freezes about 10 times a winter though, and we occasionally get ice and very rarely 1/8 inch of snow. It can be warm in winter (we had to run the a/c when it got to 91 in January), but only for a day or two. Hope this helped!
