I know it's November. But check to see if there is an indoor heated pool near you.
Cardio exercise in a pool is great for recovery. Candyass already mentioned swimming, but there are also other pool activities which are good. My dad - after his last bout with paralysis then another back surgery did several months of
resistance training in a pool before he was allowed to do it in the gym. Now instead of paralyzed from the waist down, he just got back from setting up his south carolina hunting camp for upcoming deer season. Definitely things you can do in a pool. Exactly what things for your body, with your individual case - ask your doc or PT.
