The weather in Atlanta, Houston, Austin, and Phoenix is brutally hot and/or humid and shows no sign of getting a cooler average.

It's difficult to do stuff outside when it's that hot, especially as you get older.

(True also for Los Angeles, though at least that has the Pacific Ocean)

This is the (not so?) subtle quality-of-life aspect that people seem to forget when mentioning other cities as alternatives.

The Bay Area isn't popular/expensive solely due to network effects. Climate and geography (nearness to ocean, mountains) make it comparitively more appealing than the alternatives, for a variety of ages and lifestyles.

Austin is way nicer than Houston or Phoenix, not sure about Atlanta. Acutally Austin/San Antonio pretty much has the nicest weather in texas. I'm from fort worth and fort worth gets both hotter and colder than austin - climate wise it's the california of texas (austin also has comfortable levels of humidity unlike houston).
