Ok, let me see if I can help?
Southern California can be warm all year round however there are sometimes when we get cold fronts just like everyone else and it can get down right chilly 35 at night and 50 during the day that is about as low as it goes, during the winter at the ocean. But you never know, check with the weather channel as we have had Christmas and New Years days in the 80 and nights in 60. Our motto is layer clothing. Have you ever heard the saying California is the only state where they have frost on the roses. We are going to Mexico on the Pride January 16, I will be bring all kinds of clothing from shorts to jackets rather be safe than sorry, I always over pack anyway.
