If it is just a little vapor then it is normal, the change of seasons makes it more noticeable, it is just condensation buildup in the exhaust system, however if it becomes a dense cloud of vapor and has a scent of coolant then it could be a blown headgasket, you will also notice a consumption of coolant and a possible slight engine miss on an initial start after setting overnight.
