At the Arctic Circle's latitude (approximately 66.5°N), the sun remains above the horizon for 24 hours on the summer solstice, which occurs around June 21st. As you travel further north, the number of days with continuous sunlight increases. For example, in Utqiaġvik (Barrow), the northernmost city in Alaska, the sun stays above the horizon for approximately 82 days, from around May 11th to August 2nd.
In the winter, this region experiences the Polar Night, an extended period of darkness where the sun does not rise above the horizon. In Utqiaġvik, the Polar Night is approximately 67 days.

Winter: The extreme cold features temperatures of -40-0°F (-40- -18°C) and minimal precipitation. The Polar Night plunges the region into darkness for 24 hours a day in December. While the Polar Night may seem daunting, it offers a unique opportunity to witness the enchanting beauty of the Northern Lights, also known as the Aurora Borealis.
