September is the wettest month of the year in Alaska as the short autumn season finds its way in the beautiful state. As the sunlight decreases rapidly to last only 4 hours a day, the temperatures decrease steadily, with an uptick in rainfall. The average temperatures are in the mild to cold 41°F (5°C) to 48°F (8.9°C) zone, with snowfall to the tune of 4.4" (112mm) statewide. The humidity is at the highest of the year at 82%, out of which mornings are typically the most humid. The arrival of the snow sends wildlife scampering in search of food to prepare for the onset of the harsh winter. Dawn and dusk are the best times to spot animals in the wild. September in Alaska presses insulated jackets, hats, gloves, and layers of clothing into action. The leaves begin to change colors by mid-September to further enhance the beauty of the serene landscape. Expect the temperatures to drop rapidly with each passing day in September in Alaska.
