Northern Alaska has earned its reputation for chilly days and nights. The year-round average high temperature in Barrow, the northernmost city, is 15.3 degrees, for example, and the average yearly low temperature is 4.5 degrees.
But the region is not a year-round icebox. In protected areas south of the Brooks Range, such as in Kobuk Valley National Park, temperatures may surpass 70 degrees several times a summer.
Here are monthly averages -- high temperature, low temperature, precipitation (rain and melted snow), snowfall and snow depth for Northern locations: Arctic Village, Barrow, Barter Island, Bettles, Cape Lisburne, Kobuk, Kotzebue, Kuparuk, Prudhoe Bay/Deadhorse, Umiat and Wainwright.
