Cinque Terre towns in off-season


I would like to visit the Cinque Terre towns, but I would rather not be there in the summer during the height of their tourist season. If I were to go in spring or fall, can anyone tell me what kind of weather I can expect? What is the general atmosphere of these towns during that time of year? I can’t wait to walk the trails between the different towns and taste the wine there. I hear it’s exceptional!
