It'll get in the 30's from time to time. Usually high 40's too low 50's, unless its overcast then it may only dip to 52 or so. I ride no matter the temps as long as its dry. last year on Mt hamilton there was snow on the ground, yes it was damn cold, but it was still a great ride. I will aclimate to our weather and your will feel warm. Remember, I work outside in a shop for 1o hours a day so I get tortured throught the winter.
