The only way to get it is to live at 5000 ft elevation up in the mountains about 100 miles North of Phoenix..about 15-18 degrees cooler than Phx, and love the low humidity vs. Dallas.
I live about sea level in the Mohave Desert in AZ and the heat here (I have seen 133 degrees) is much hotter than when I lived in Houston. But I do have to say the its not the heat its the humidity arguement has some merit and you can get a tan in 15 seconds.
