They can be fine in Southern CA weather, but the pet would require a bit more attention, as far as getting groomed a bit more often, to make sure his/her hair was short enough etc..
Huskies are known for their ability to adapt to each extreme of a climate change. While they prefer colder weather, they have no problem, if cared for properly, adapting to warmer weather.
It really depends on how much time and responsibility you're willing to share with the animal. Believe me though Huskies are true companions, and will literally become your best friend.
