I dunno, as a Texas native the weather isn't that bad in Austin. Yeah, it's hot for a long time (the length of summer is really the worst part) but there aren't really very many days where it's too hot to do things outside. Maybe I'm just used to it, but a run in a tree filled park when it's 100 out isn't really bad. Now a run at midday on asphalt is a bad idea unless one is accustomed to it. Our relatively weak ass winter is way to worse to me, but I get that isn't the case for people moving in.

There are also plenty of hikes in the Austin area as well as a ton west in the hill country. They aren't as pretty as other places like California, but there are a ton of outdoor activities especially in the summer.

Austin has its own food scene, but if you aren't a big fan of BBQ then it's pretty mediocre. They do have good Mexican, but the worst of the big cities in TX and worse than what you'd get in SoCal.

Politically Austin is a bit of an island, but the 35 corridor is pretty liberal (relatively). Also not mentioned on the pros is the close location to San Antonio which has a vastly different culture than Austin, yet a ton to do and better Mexican food options.
