I had to spend 6 months TDY, May-Oct, in SoCal while working on a DoD contract for my company in early ‘80s.
Weather was hot and miserable every day; no change until late in the evening when it got cool and everyone hit the heated Jacuzzi pool in the courtyard at our motel about 10-11pm, after spending a few hours at the bars. Breakfast for us at outdoor restaurant tables had space heaters every few feet. ...Having to wear suits and ties in the daytime was miserable.
I’ll take DFW area weather over that, even though the Northers that blow in do make it cold for a spell.
I’ll take So. Cal summer weather over DFW scorchers. Although it does rain in summer just a little bit vs zilch in So. Cal.
While in college, I spent 2 summers with my sister in Dallas. It was a nice & had a lot of fun, but very hot & humid. You go from an air conditioned house to your air conditioned car, to your air conditioned destination. Used to play golf with a friend and many times the club would fly out of my hand because it was so sweaty.
I lived in Houston for a year, and it was even more humid than Dallas.
I have lived in my house in Huntington Beach for 20 years and have never turned on the A/C or heater. For a few weeks during the summer we use the overhead fans.
I wear shorts & t-shirts pretty much 365 days a year. I put a sweatshirt in my car & put it on as necessary, but that is about all.
