Imagine a world where the sun doesn’t rise for weeks or even months. This phenomenon, known as Polar Night, occurs in the polar regions, inside the Arctic and Antarctic Circles. During this time, parts of the world experience long, dark days and nights, with little to no sunlight. This event is a striking contrast to the Midnight Sun, when the sun never sets during the summer months in these regions.
Understanding Polar Night is important for anyone interested in the natural world, travel, or unique weather phenomena. Let’s dive into what Polar Night is, when it starts, and the places where you can experience this extraordinary event.

What is Polar Night?
Polar Night is a period of darkness that occurs in the polar regions, where the sun does not rise above the horizon for an extended period. This happens due to the tilt of the Earth’s axis, which causes one hemisphere to be tilted away from the sun for several months at a time.
For those living in the Arctic Circle, the days leading up to Polar Night gradually get shorter until, during the winter solstice, the sun does not rise for an extended period. The length of this period varies depending on how far north (in the Arctic) or south (in the Antarctic) you go.
Unlike other parts of the world, where daylight gradually fades as winter approaches, the Polar Night is defined by complete or near-complete darkness. The sky often remains a twilight blue during the day, but no direct sunlight reaches the ground.
When Does Polar Night Start?
The beginning of Polar Night depends on your location. It starts on different dates depending on how far north or south you are in the polar regions. In general, Polar Night begins just after the autumn equinox, which occurs around September 22 each year. However, the precise starting date varies across different locations within the Arctic and Antarctic Circles.
In places like Svalbard (Norway) or Barrow (Alaska), the Polar Night can begin in late October or early November. These locations are situated far enough north that they experience several weeks or months of continuous darkness. Conversely, areas closer to the Arctic Circle, like Fairbanks, Alaska, may only experience shorter periods of darkness.
In the Antarctic region, the situation is similar, but it occurs during the Southern Hemisphere’s winter months, from late May to late July. During this time, the South Pole remains in constant darkness.
Why Does Polar Night Happen?
Polar Night happens because of the Earth’s tilt on its axis. Earth is tilted at an angle of approximately 23.5 degrees, which means that during certain times of the year, the poles are either tilted toward or away from the sun.
During the winter months in the Northern Hemisphere, the North Pole is tilted away from the sun, causing the sun to remain below the horizon for months. Similarly, during the Southern Hemisphere’s winter, the South Pole is tilted away from the sun. As a result, these areas experience Polar Night.
This period of darkness can last for a few days to several months, depending on the exact location. The further north or south you are, the longer the Polar Night lasts. At the North and South Poles themselves, the night can last up to six months.
Where Can You Experience Polar Night?
Polar Night occurs in both the Arctic Circle (Northern Hemisphere) and the Antarctic Circle (Southern Hemisphere). Some of the best places to witness Polar Night are:
1. Tromsø, Norway
Located 350 kilometers above the Arctic Circle, Tromsø experiences Polar Night from late November to mid-January. This charming city is famous for its stunning natural beauty and the Northern Lights, making it a prime destination for travelers hoping to see the Polar Night in all its glory.
2. Svalbard, Norway
Svalbard, a Norwegian archipelago, has some of the longest and darkest Polar Nights in the world. The darkness here lasts from late October until mid-February. The archipelago is remote, offering a unique opportunity to experience the profound quiet and tranquility of extended darkness.
3. Barrow (Utqiaġvik), Alaska
Utqiaġvik, formerly known as Barrow, is the northernmost city in the United States. It experiences complete darkness from November 18 to January 23 each year. Visitors to Barrow can experience the beauty of Polar Night and also have a chance to see the Northern Lights.
4. Fairbanks, Alaska
Fairbanks offers a shorter version of the Polar Night. The city experiences long nights from late November to January, with only a few hours of twilight each day. Despite the limited sunlight, it’s a great location to catch a glimpse of the aurora borealis.
5. Rovaniemi, Finland
Rovaniemi, located in the Finnish Lapland, is another excellent destination to experience Polar Night. From early December to early January, this area is plunged into darkness, but it offers plenty of winter activities like husky sledding and the chance to visit Santa Claus Village.
6. Reykjavík, Iceland
Iceland’s capital, Reykjavík, experiences shorter but notable Polar Nights. The darkest period is between late November and mid-January, where the sun rises only briefly for a few hours each day.
7. Antarctica
In the Southern Hemisphere, the Polar Night occurs during the winter months of May to July. The South Pole, situated on a high plateau, is in total darkness for about six months. Visitors to Antarctica can witness this period if they travel during these months, although tourism is limited due to the harsh conditions.
What to Expect During Polar Night
During Polar Night, the landscape often looks eerily beautiful. The constant twilight creates a surreal atmosphere. The lack of direct sunlight can result in colder temperatures, and the snow-covered landscapes are bathed in soft, dim light from the moon and stars.
While it’s dark for most of the day, the sky can still offer stunning views of the Northern Lights in the Arctic or the Aurora Australis in the Antarctic. These lights, caused by solar winds colliding with Earth’s atmosphere, create vibrant green, pink, and purple patterns in the sky.
Many people report that the Polar Night brings a sense of peace and quiet. The long, dark days offer an opportunity for reflection and relaxation, but they can also be challenging. Some people may experience symptoms of Seasonal Affective Disorder (SAD), due to the lack of sunlight.
Activities to Enjoy During Polar Night
While it may be dark, Polar Night provides the perfect opportunity for activities that require little to no daylight:
- Northern Lights Viewing: This is one of the most popular activities in Polar Night regions, especially in places like Tromsø, Alaska, and Finland. The darkness allows for the best visibility of the auroras.
- Dog Sledding and Snowmobiling: Many Arctic regions offer these thrilling winter sports, which are great ways to explore the snowy landscapes.
- Ice Fishing and Skiing: Activities like ice fishing and cross-country skiing are popular during the Polar Night.
- Visiting Ice Hotels and Igloos: In places like Finland and Sweden, you can stay in ice hotels or igloos, experiencing a unique and cozy winter getaway.
