I only mention the travel times so you can plan accordingly. I don't want to see you get hung up in traffic like so many people do.
It's Southern California, not central Kansas, some don't realize the difference.

PS
several weather websites will let you look back in history for weather in certain locations, give that a shot.

February is supposed to be winter and the rainy season. Although I don't think it rained at all this February, we were deluged in 2005. There is almost never any frost, night time temps about the 40's to 50's, Daytime could be anywhere from 50's to 70's, occasionally more. Sweater and jacket weather, bring rain gear of some type.
