Texans complain about the weather too much. Where else can you have 100 degree heat and lush green grass everywhere you go because it rains all the time in the summer?
Arizona feels good, but I can't take the ugly brown scenery. Besides, that dry air isn't doing anything good for your skin.
To me, the temperature doesn't really make a difference. It's whether the sun is out or not. I'm hotter in the sun in March than I am in the shade in August. That's probably due to my skin being so light though. I get a sunburn making toast in the morning.
Honestly though, the majority of Texans don't know what unbearable heat is. Yes, I said it. They don't. Air conditioned homes, jobs, cars, shopping centers, restaurants, etc. Plus if you don't have A/C or yours breaks, it's easy to find and cheap to buy. Now go live in a northern state when it's 94 degrees and you have no A/C at home/car/job and then see how you like things. Want to buy some? Every store is sold out and won't have more for months. I asked Home Depot in June one time when they were going to get more air conditioners....September. What if you ordered one....You could but it will still get here in September.
When the thermometer in your home in TX reads 75 instead of 70 beacause it's hot outside, that's not all that bad. You can still sleep easily at night. You don't have mosquitos to deal with because unlike in the north, you don't have every window and door open. (Yes screens help, but they always seem to get in somehow)
Tint your car and get some good A/C running through it and you'll do fine in Texas. Austin feels like Phoenix after you've been in Houston for awhile anyways. Dry and nice to walk around in.
I've been in heatwaves so bad, I couldn't even understand my email. I'd read it to myself 3 times in a row but just couldn't make out what the message was saying. So hot at night, you can't get to sleep before 1AM (and the alarm goes off at 4:15AM) Sleeping during the afternoon is futile. You try gettingy by on 3 hours sleep a night for a few weeks while experiencing heat during the day. Driving a car that's on average 120-130 inside.
Summer is the best time in Texas....because it's so cool and comfortable.
