Everyone down for the summer?

I don't know how you guys do it down there... My wife called me while on her way to Texas, it was 112 in Needles, Ca.
I took some winter vaca in Palm Springs in Nov 2017. It was 85 still. Water slides were 'closed for winter'. WHAT?

One of the guys in Phoenix a week or so ago showed a pic of his truck thermometer and it said 120.
He said some of that might be off the pavement and I said it didn't matter where it was coming from, as that's just hot.
