I was in LA last year trying to do my Global Entry crap in Feb when it was 30 at LAX. That was pretty damn chilly for SoCal. It hit 29 up in SFO where I live. But that was just a couple of days.

This is the most temperate place I've ever lived. Winter....low 40's at nite, maybe hi 30's. Days mid 50's/low 60's. Summer....60's/low 70's at nite, upper 70's/mid 80's day. Pretty much never changes from that the entire year + that I've been here.
