JojoK,
Welcome to the Forum!
Be sure to read what others and I have written re late autumn/winter walking in this earlier Forum thread. Each link leads to further useful info.

When walking in late autumn/winter only in larger places such as Roncevalles, Logrono and Santo Domingo de la Calzada and, of course, Santiago have I ever seen a cluster of more than 20 pilgrims at one time. It is easy to walk alone and in smaller albergues you might be the only pilgrim.
Most of us who walk in late autumn and winter wear and carry lightweight but warm layers which can easily be added or removed while walking. Each pilgrim develops a favorite combo. Scan the Forum's
Equipment topic to see a multitude of varied approaches.

It is a great time to walk but you must be prepared.
Good luck and Buen camimo!
