Being in South California means you should limit your expectations about seasons. There would be no winter and now in early February, here comes the Spring season!
I took this photo last week in Marguerite Parkway in Mission Viejo, Orange County. Now all fruit trees are decorated with little beautiful flowers and make an exceptional scene to visit. If you are living near such area, it is good to take your car and have some time driving around here and enjoy the scene (walking? well, I really don`t recommend it if you don`t live around this area!).
If you are adventurous enough and have time, take the road to south and down to highway 5, and you will arrive at Dana Point bay and Pacific coast Highway, which is one the most beautiful roads to drive in US.
