I used to live in Sherman Oaks! Great weather most of the time....summer sucked bellybutton being in that bowl that is the valley though. 
Yes it does, but thankfully I hide in West LA near Santa Monica in a building with industrial-sized air conditioning to shield me during the worst hours of the day five days outa the week. But it's not like my apartment is nice n' cool when I get home, it's on the top floor on the side of the building facing south. Gotta leave the windows (that I can without compromising security) open for my pet when I'm gone during the day.
Frigin hate this time of year. I'm always looking to the North though, it just gets prettier and cooler the further you go.
Edit: ok on second thought, it's not that bad, there's more half-naked women than you can count on your figners and toes looking in any single given direction this time of year.
