Where in Alaska Does It Stay Dark?
In northern Alaska, towns like Utqiagvik (formerly Barrow) experience polar night, a period when the sun does not rise above the horizon for weeks or months. This happens because the Earth’s tilt keeps the region angled away from direct sunlight during winter. Fairbanks and other interior cities also have very short daylight hours, but they still see brief sunrises and sunsets.
Why Does It Stay Dark for So Long?
Alaska’s darkness is caused by the planet’s axial tilt. During winter, the North Pole points away from the sun, so locations above the Arctic Circle receive little or no direct sunlight. The farther north you go, the longer the period of darkness. In Utqiagvik, polar night can last about 65 days, while areas slightly south may have only a few weeks of very limited daylight.
How Long Does the Darkness Last?
The length of darkness depends on latitude. Utqiagvik usually has about 65 days without sunrise, while Fairbanks may have only a few weeks of very short days. As you move south toward Anchorage and Juneau, daylight returns more quickly, though winter days remain short. Seasonal patterns repeat each year based on Earth’s orbit and tilt.
