Houston has many great qualities and is a great place to live - except for one thing.
The humidity.
You know you're approaching summer in Houston when you walk outside and instantly burst into a heavy sweat. Ten minutes outside and you've got perspiration stains on your back, under your arms, etc. Step out of your car or front door and your glasses are immediately fogged up so bad you can't see.
I roofed my house one year during August. I was drinking over three gallons of Gatorade a day, and didn't have to take a leak even once !
When I moved here from Seattle, my wife and I drove to Houston in our un-airconditioned Mustang. Even prior to finding a house, the first thing we did was go out and buy an airconditioned car.
I left Houston one day when it was 85 degrees and absolutely miserable to be outside. I landed in Phoenix, where it was 102. It was so comfortable by comparison I went for a walk outdoors !
This scenario exists for about six months out of the year.
When we moved to Houston (1972) my husband had been down there many times on business and always spoke highly of it. We accepted the transfer from California without a second thought. Then, the company sent me down to look for a house. The plane was delayed and we arrived around midnight. Something was wrong with the jetway at Houston Intenational Airport (now George H. W. Bush airport) and we couldn't leave our plane directly into the airport. We sat parked on the tarmac for over an hour waiting while they fiddled with the controls. Finally they wheeled out portable stairs so we could get off the plane.
In the mean time they had turned off the engines so there was no AC on the plane. We were choking with heat by the time they finally let us out. I remember climbing down those stairs and feeling the humidity just hit me in the face as we crossed the tarmac to the cool sanctuary of the airport. It was about 1:30 AM and I remember it felt like I was walking into the basement laundry room of a hospital, it was so hot and sticky! Right then I thought, "Oh no, I've made a terrible mistake agreeing to this move!"
We were moving from a mild northern California climate but we finally got used to it. It took about a year before I dared to go outside in the daytime, except in my air conditioned car. I grew to love the Texas heat, however, and the Texas people. All my kids were educated in Texas. I've been gone from there 22 years, and I still miss it -- except for the AC bills and the traffic.
