On clear winter nights, the aurora borealis can often be seen dancing in the sky. Like all subarctic regions, the months from May to July in the summer have no night, only a twilight during the night hours. The months of November to January have little daylight. Fairbanks receives an average 21 hours of daylight between May 10 and August 2 each summer, and an average of less than four hours of daylight between November 18 and January 24 each winter.
