I can totally identify with the OP (I live in the same area).
I brewed a few days ago when it got up to 100 degrees. I sweat A LOT, so I have to be careful not to sweat into my brew kettle (not that it would change the beer or anything. I just don't like the idea of sweating like crazy into my wort).
I used my immersion chiller to get it down to about 86 or so. When the ambient temperature is 100, the ground water is going to be pretty warm. Then I used ice I bought from the convenience store to chill it down to 72. Pitched my yeast, then lowered the temperature down to 67, and have kept it there since.
I'm not a fan of brewing in the heat, but you can't control the weather, so why not?
