Remember that "rho" factor in the equation for aero drag. "Rho" is the density of the air.
Cold winter air can be up to 20% denser than warm, humid air, hence more aero drag in winter.
People drive differently in winter. Not getting stuck is kinda important. Also on slick roads you have to put much more emphasis on avoiding bent-up sheet metal. For me that cuts down on my coasting.
Solution: Move to Houston.
