Weather and planning

Hello all: planning a wedding for next October because I want it outside near the beach or possibly up in the hills at a winery in southern Ca. I was picking early fall to be more sure of the weather for an outside ceremony. I see many at one of my outside venues had wedding dates in winter and early spring and all outside. I don’t live in CA and only really know from spending a lot of time there that October is still warm and even December this year was ok with rain though. My question is, is it realistic to plan a winter or spring or even November wedding, weather wise in southern CA? Did you have back up plans for something indoors for the rain? Crazy as it sounds, I can’t help but think of smoke being an issue as every year we are there it is smokey and I would not want guests in that outside if we choose a location at a winery. Thanks for any thoughts.
