How long will you be here? What do you want to do? Do you just want to be near the City of SF, or looking for other areas too? We are near Santa Cruz, it's pretty chill here and lots of great hiking, beach walks, etc. The further north you go from So Cal the more rain you get. Seacliff is great...but sometimes you get kicked out because of the high tides/waves at that time of the year, but you can still stay in the upper parking lot. Pismo is great that time of the year too. When it rainy here, it's not always rainy there. Some 70 degree days there during that time frame is possible.
