I'm a texan too of almost 3 years, and the weather is disgusting here. Depending on where I lived in my life is depending on what time of the year I love most so here is my run down according to states I've lived in:
Texas: Late November through February, it's finally cool and my kids can go outside to play!!
Minnesota: October and summers. October it isn't too cold yet and it has the smell of crisp autumn leaves, love it. Then summers are so pleasant. You can actually sit outside in the shade and not sweat and when the sun sets, the nights cool off and sitting outside with fresh lemonade watching fireflies is perfect.
Utah: December, nothing like a guaranteed snow fall for Christmas! However, if it's summer and you need to cool off, you just head up through the canyons to waterfalls/rivers and play the day away.
California: (southern) It's temperate climate makes for a year round blissful time. But, it can get depressing with no snow for Christmas (just like here in TX:().
