Alaska's climate is significantly affected by its northern latitude, which results in colder temperatures and extreme seasonal variations.

Alaska’s climate is heavily influenced by its northern latitude, which positions it closer to the Arctic Circle. This high latitude means Alaska receives less direct sunlight, especially during winter months, resulting in colder temperatures and long, dark winters. The northern latitude also causes extreme seasonal variations, with lengthy daylight hours in summer and limited sunlight in winter. While ocean currents and elevation also impact Alaska’s climate, its northern latitude is the primary reason for its cold temperatures and unique seasonal daylight patterns, distinguishing it from other U.S. regions.
