Arctic Circle — World Map, Countries It Crosses, and Geographic Facts
By Marko Visic · Updated Oct 3, 2026
The Arctic Circle is the parallel of latitude at 66°34′N — the southernmost point on Earth where the sun can stay above the horizon for 24 hours on the June solstice (the midnight sun) or below it for 24 hours on the December solstice (the polar night). At 15,984 km long, it crosses 8 countries.

Quick facts
- On the June solstice, the sun stays above the horizon for 24 hours at every point on the Arctic Circle — the "midnight sun".
- On the December solstice, the sun never rises at the Arctic Circle — the "polar night" lasts the full day.
- The Arctic Circle drifts toward the pole at about 14.5 meters per year as Earth’s axial tilt oscillates — the line is not geologically fixed.
- Rovaniemi, Finland advertises itself as the "official hometown of Santa Claus" because of its Arctic-Circle position.
- More than four million people live in the northern regions of the eight Arctic states, most of them in Russia.
- The total land area enclosed by the Arctic Circle is roughly 20 million km² — almost twice the area of Europe.
What is the Arctic Circle? Definition and Geographic Facts
The Arctic Circle is one of the five major parallels of latitude on Earth. By definition, it is the southernmost latitude at which the sun can remain above the horizon for a full 24 hours — the “midnight sun” — on the June solstice, and remain below the horizon for a full 24 hours — the “polar night” — on the December solstice. North of the Arctic Circle, the duration of polar day and polar night extends with latitude; at the North Pole itself, the sun is up for six months and down for six months.
Arctic Circle definition (short): the parallel of latitude at 66°34′N marking the southern boundary of the Arctic. Arctic Circle latitude: 66.5641° (decimal degrees), set by 90° minus Earth's axial tilt of about 23.4°. Arctic Circle length: 15,984 km (9,932 mi) — only about 40% the length of the Equator, because it is a small circle close to the pole rather than a great circle.
Where is the Arctic Circle on a world map? On any standard world map, the Arctic Circle is the horizontal line near the top of the visible world, just below the polar ice region. It runs west-to-east across northern Scandinavia (Norway, Sweden, Finland), the immense north of Russia (about 6,700 km of land), the Arctic Ocean, northern Alaska, northern Canada, northern Greenland, and just clips Iceland's Grímsey island before completing its 15,984 km loop.
Astronomically, the Arctic Circle defines the polar regions — north of the line, the sun is below the horizon during winter for at least one day, and above it during summer for at least one day. Climatologically, it roughly corresponds to the boundary between the subarctic taiga forest belt and the treeless tundra, though the exact tree line varies by 100-200 km depending on local conditions. More than four million people live in the northern regions of the eight Arctic states — a wider area than the circle encloses, per the Arctic Council — most of them in Russia.
How to use this Arctic Circle map

The 8 countries the Arctic Circle passes through
From west to east, here is what the Arctic Circle passes through in each country, with the landmarks, towns, and ecological zones along the line.
Norway
The Arctic Circle enters Norway on the Atlantic coast in Nordland County and crosses the country east toward the Swedish border. The Arctic Circle Centre at Saltfjellet, on the E6 highway, marks the line with a visitor center, monument, and museum. The town of Mo i Rana sits roughly on the line; further north, Bodø and the Lofoten Islands are also north of the Arctic Circle and are popular for midnight-sun and northern-lights tourism.
Sweden
The Arctic Circle crosses Sweden through Norrbotten County in the country's far north, just south of the town of Jokkmokk and through the western part of the Sami homeland. Jokkmokk is famous for its Winter Market, a 400-year-old Sami trade fair held every February. The line continues east toward the Finnish border at the Torne River.
Finland
Rovaniemi, Finland's largest city in the Arctic, sits almost exactly on the Arctic Circle and advertises itself as the official hometown of Santa Claus. The Santa Claus Village complex on the line is one of the most-visited Arctic-region tourist sites globally. The line continues east through Finnish Lapland to the Russian border.
Russia
Russia hosts by far the longest Arctic Circle stretch of any country — about 6,700 km from Karelia in the west to Chukotka in the far east, crossing roughly 11 federal subjects. The line passes through Murmansk Oblast (with the city of Murmansk just north of the line), the Komi Republic, the Yamalo-Nenets Autonomous Okrug (gas-rich tundra), Krasnoyarsk Krai (including the Putorana Plateau), the Sakha Republic, and Chukotka. Roughly 2 million people live north of the Arctic Circle in Russia — the largest Arctic population of any country.
United States
The Arctic Circle crosses the north tip of the Seward Peninsula and Kotzebue Sound, then the mainland east to the Yukon border. The Dalton Highway crosses it at milepost 115, at the BLM's Arctic Circle Wayside. Utqiagvik (formerly Barrow), the northernmost town in the United States, lies far north of the line.
Canada
The Arctic Circle crosses Canada through Yukon, the Northwest Territories, and Nunavut, covering about 3,100 km of subarctic and tundra terrain. The Dempster Highway in Yukon crosses the line at a marked visitor stop, and the town of Inuvik in the Northwest Territories lies about 200 km north of the line. The Canadian Arctic Archipelago — Banks, Victoria, Baffin, Ellesmere — is entirely north of the line.
Greenland
Greenland (a Danish autonomous territory) is crossed by the Arctic Circle on both its western and eastern coasts, with the central Greenland Ice Sheet entirely north of the line. Sisimiut, Greenland's second-largest town, sits just north of the Arctic Circle on the west coast. The Arctic Circle Trail — a popular long-distance hiking route — runs roughly along the line from Sisimiut west toward the ice sheet edge at Kangerlussuaq.
Iceland
Mainland Iceland is entirely just south of the Arctic Circle — the northernmost point of the mainland is Hraunhafnartangi at 66.53°N, about 4 km south of the line. The only Icelandic territory on the Arctic Circle is Grímsey, a small island 40 km north of the mainland with a population of about 60. A monument and painted line on Grímsey mark the exact crossing, and visitors who walk across the line receive an official certificate from the local council.
Climate at the Arctic Circle: tundra, taiga, and the North Atlantic Drift
Climates along the Arctic Circle are dominated by two regimes: subarctic continental (Köppen Dfc, “snow-forest with cool summers”) and tundra (Köppen ET). Subarctic Dfc covers most of inland Scandinavia, northern Russia, and continental Canada; the climate features long cold winters (-25°C to -50°C lows are common in interior Russia and Canada), short cool summers (10-15°C average highs), and dense conifer forests that survive the deep cold but cannot cross to the tundra zone north of the tree line.
Coastal and high-Arctic regions (northern Alaska, Greenland, Canadian Arctic Archipelago, northern Russia) are tundra — too cold and dry for trees, dominated by mosses, lichens, sedges, and dwarf shrubs. The growing season is 50-80 days. Tundra soils are often permafrost (permanently frozen ground), which creates distinctive features: pingos, ice wedges, thermokarst lakes, and the seasonal active layer that supports plant growth in summer.
The most striking climatic feature near the Arctic Circle is the North Atlantic Drift — a warm ocean current that brings ice-free harbours and mild winters to Norway and northwestern Russia at latitudes where interior Siberia or Alaska would be deeply frozen. Murmansk in Russia is an ice-free port at 69°N (about 270 km north of the Arctic Circle); the Lofoten Islands in Norway have winter average temperatures above freezing despite sitting at 68°N. Without the Drift, northern Europe would have a climate similar to interior Canada at the same latitude.
The midnight sun and the polar night
The Arctic Circle is defined by two astronomical phenomena: the midnight sun on the June solstice (the sun stays above the horizon for 24 hours) and the polar night on the December solstice (the sun stays below the horizon for 24 hours). Exactly on the Arctic Circle, each phenomenon happens on a single day per year. North of the line, the duration extends; south of the line, neither happens.
At 72°N (interior Russia, northern Greenland, Canadian Arctic Archipelago), polar day extends for about 70 days and polar night for about 70 days. At 80°N, polar day is about 130 days and polar night about 130 days. At the North Pole, polar day and polar night are each 6 months long.
The midnight sun has practical and cultural consequences: Tromsø, Norway, hosts a Midnight Sun Marathon every June 21; the sun's 24-hour presence enables agriculture in Lapland (potatoes, hardy grains) at latitudes that would otherwise be too cold; Indigenous Arctic peoples have developed millennia-old adaptations to seasonal extremes, including polar-night hunting traditions in Inuit and Yupik communities.
The Arctic Circle is moving (slowly)
The Arctic Circle is not geologically fixed in latitude. Over the last million years Earth's axial tilt has ranged between 22.1° and 24.5° in a cycle of about 41,000 years — one of the NASA-documented Milankovitch cycles that drive ice ages; it is slowly decreasing and will reach its minimum about 10,000 years from now. The Arctic Circle latitude equals 90° minus the tilt, so it shifts in step: at minimum tilt (22.1°), the Arctic Circle is at 67.9°N; at maximum tilt (24.5°), it is at 65.5°N. The total shift is about 270 km of latitude.
The current rate of movement is about 14.5 meters per year toward the pole, and will continue for several thousand more years before reversing. On a human timescale this is invisible, but over millennia it has practical effects: the official Arctic Circle latitude used on maps is updated every few decades to track the IAU value, and a monument placed on the line in 1900 is now about 1.7 km south of the current line.
Where to stand on the Arctic Circle: monuments and visitor sites
The Arctic Circle is one of the most heavily-marked latitude lines on Earth — every country it crosses has at least one official visitor monument. The most famous is the Arctic Circle Centre at Saltfjellet, Norway, on the E6 highway between Bodø and Mo i Rana. Rovaniemi, Finland, has the Santa Claus Village directly on the line — one of the most-visited Arctic-region tourist destinations globally. Sweden's crossing is marked at the Norrbotten visitor center near Jokkmokk; Russia has multiple monuments along the Salekhard rail line; Canada's most-visited Arctic Circle marker is on the Dempster Highway in Yukon; in Alaska the Dalton Highway crosses the line at milepost 115, at the BLM's Arctic Circle Wayside. Greenland's Arctic Circle Trail is the longest marked Arctic-Circle hiking route in the world. And Iceland's tiny Grímsey island offers visitors a printed certificate for crossing the line on foot.

Data sources & methodology
Country list and per-country length: the line was intersected with every country polygon from Natural Earth 1:10m Admin 0 (v5.1.2, public domain). Lengths are measured on the WGS-84 ellipsoid (arc of the parallel) and rounded to the nearest kilometer; coordinates are rounded to 0.01°. Floating ice shelves are not land in this dataset, and 1:10m coastline detail can move a figure by a few km. Iceland's mainland is just south of the line; only Grímsey island (population ~60) is officially on the Arctic Circle.
Latitude: 66°33′51″N (66.5641° decimal). Equal to 90° minus Earth's axial tilt; the line drifts toward the pole at about 14.5 meters per year.
