December is a cold time for the majority of the United States. Hence, many states will see extensive snowstorms or heavy rainstorms. It makes the holiday season slightly more uncomfortable than the other calendar months.

But which states are the coldest? Today, we will answer that question. We are here to showcase the 10 coldest states in December while illustrating the average monthly temperatures they experience. Additionally, we will use data compiled by Extreme Weather Watch from the National Oceanic and Atmospheric Administration on a 20-year model.

To show you just how cold some states are, several states you would not believe just missed making the top-10 list. Those states were Michigan, Iowa, New Hampshire, New York, and Washington, finishing 11-15.
