Not sure how to answer that. For one, we really don't go into Austin much. We spend a majority of our time in the suburbs (Leander, Cedar Park, ...). I also think when I said "South Bay" that you might have thought I meant somewhere in So. CA. If that is the case, sorry. I am so used to "South Bay" being San Jose, Santa Clara, Sunnyvale, Cupertino, Campbell, Saratoga ...Austin is one place we’ve considered if we ever leave So CA. How wound you compare the lifestyle?
Since we arrived in Texas in late October 2018, we haven't lived through a Texas summer yet. Really don't know how that's going to go. Both my wife and I were born and raised in the Central Valley of California, which can get quite hot in the summer, but not like in Texas.
