I walked the
Camino Frances from Sept. 30 to Nov. 17 last year. I carried a fairly warm sleeping bag, which was really more than I needed. This year, I am going again, beginning a couple of weeks earlier and finishing a week earlier. I have changed to a lighter weight sleeping bag and will be spraying it with permethrin against bed bugs and wearing merino wool tights and shirt if needed. Whether you are warm enough is something no one else can really decide. Are you leaving at the beginning of September or nearer the end? Do you sleep warm or cold? How warm is your microfleece blanket? Have you tried out your sleeping gear for comfort and warmth? It can get pretty chilly in the autumn on the Frances. The heat may not be turned on until November. On the other hand, Spanish and French pilgrims often seem to be allergic to fresh air and will seal the windows shut. And of course, the body heat put out by a group of people in a small dormitory packed with bunks can be considerable. Good luck whatever you decide.
