It averages out IMO. In my Model 3 AWD in the Midwest, I frequently get better than the rated efficiency of ~242 Wh/mi in the summer and Fall and worse in the winter. It is around ~200 Wh/mi in the summer and close to 300 in the winter depending on how cold it gets. So the range could be as low as 250 in the winter and even better than 310 in the summer/fall depending on how I drive and how warm it is.
