Alaska experiences the coldest average temperatures in the U.S. due to its northern latitude.

Alaska is the coldest U.S. state on average because of its northern latitude, placing it close to the Arctic Circle. This high latitude results in long, cold winters with significantly lower temperatures, particularly in the interior and northern parts of the state. Alaska experiences shorter days and longer nights during the winter, which contributes to its colder climate. Unlike states like Texas, California, and Florida, which are much farther south and enjoy milder climates, Alaska’s position at the extreme northern edge of the country makes it the coldest state year-round, with temperatures often dipping well below freezing.
