i have been walking in late October, November and December for a long time. You NEVER know what will happen. 8 years ago on the CP from Lisbon starting in October and ending early November. No rain and temps at the beginning around 90 and later cooled down. I could count on one hand the days that were cloudy. Last year I was on the CP coastal in November and I just about swam to Santiago. But I couldn't have cared less because where would I rather be? I have been on the Meseta at exactly the same time 3 years apart. First time 90F+ and not a cloud in the sky. Second time, Rain that would hit you in the face, high winds and 40-50F every day. Just walk and accept. I don't want to intrude on your husband and your decisions about going. The camino is hard and your husband may learn what a truly wonderful experience it is or be absolutely miserable. You never know what wll happen inside and out. I say just walk and tell yourself and your husband to leave your expectations at home and accept the camino one step at a time.
