January in Alaska is synonymous with winter in its purest form. Expect extremely cold temperatures, often dipping well below freezing, and significant snowfall across much of the state. Daylight hours are at their shortest, creating long, dark nights perfect for Aurora Borealis viewing. If you're an avid winter enthusiast, January offers unparalleled opportunities for activities like dog sledding, ice fishing, and snowmobiling.
