It depends on where you are in the USA. Southern states like Florida, Texas, & Nevada stay warm all year round. Northern states like Maine, Minnesota, Michigan, Washington & North Dakota have winter temps well below freezing, and the farther north you get the colder it gets. Indiana is just south of Michigan and the temps in northern Indiana get colder than at the south Indiana border, much the same as Ohio, Illinois, etc.
