Yes, the needs certainly increase during the winter. The "snow birds" as we call them, are the elderly that come to visit to get away from harsh winters, but end up needing to be seen at a hospital. Thus our census goes up and there's usually options for over time! I'm currently staff, (and about to start traveling soon!) So I'm not sure if we have lots of travel nurses or what departments get them. I've never seen one on a med surg floor. Good luck to you!
