Yakutsk
The coldest major city on Earth, built on permafrost.
Yakutsk is the capital and largest city of Sakha, Russia, located about 450 km south of the Arctic Circle. Fueled by the mining industry, Yakutsk has become one of Russia's most rapidly growing regional cities, with a population of 355,443 at the 2021 census. Yakutsk has an average annual temperature of -8.0 C, winter high temperatures consistently well below -20 C, and a record low of -64.4 C has been recorded. As a result, Yakutsk is the coldest major city in the world (although a number of smaller towns in that region are slightly colder). Yakutsk is also the largest city located in continuous permafrost; the only other large city is Norilsk, also in Siberia. Yakutsk is in the Central Yakutian Lowland and is a major port on the Lena River. It is served by the Yakutsk Airport as well as the smaller Magan Airport.

Lore & Background
The city was founded in 1632 by the Cossacks and was originally called either the Lensky fortress or the Yakutsk fortress. The first version of the toponym came from the hydronym 'Lena'; the second, from 'Yakutia', a synonym for Sakha, eventually became the main one in use. In 1708 it received city status as Yakutsk. The territory upon which the city of Yakutsk now lies on was inhabited long before the founding of the Russian Lensky Fortress. According to archaeological data (more than 200 sites, settlements, burial sites, and other archaeological monuments have been explored within the city), the oldest of them, the Yubileinaya site, is estimated to be 20,500–10,000 years old. According to legend, the ancestors of the Yakuts, Elley Bootur and Omogoy Bai, settled on the territory of the modern city. Archaeological evidence shows the Yakuts settled the Tuymaada Valley in the 13th–16th centuries, as can be seen in the old settlements of Zernovaya-II, Orbita-16, and Vladimirovka-IV, which belong to the Kulun-Atakh archaeological culture, associated with the ancestors of the Yakuts. When the Yakuts, also known as the Sakha people, migrated to the area from other parts of Siberia, they mixed with other indigenous Siberians such as the Evenk and Yukagir. The Russian settlement of Yakutsk was originally founded in 1632 as an ostrog (fortress) by Pyotr Beketov. In 1643, when Pyotr Golovin was governor, the fort was moved to the left bank of the River Lena, in the Tuymaada Valley near Lake Saisary. It was at this location that the fort would become a town known as Yakutsk. In 2024, a corpus of written documents was discovered in Yakutsk, including 14 birch bark letters written in ink in a 17th-century cursive script (with numbers written in letters). Archaeologists believe they belong to the archives of the voivode's chancery, lost in a fire in 1700. One fragment speaks of the collection of yasak. In 2025, a paper letter-appeal was found addressed to Archimandrite Feofan, who was the abbot of the Spassky Monastery in Yakutsk from 1714 to 1719.
Reader's Guide
With an intensely continental subarctic climate (Köppen climate classification Dfc, bordering on Dfd, Trewartha Ecbd), Yakutsk has the coldest winter temperatures for any city its size or larger on Earth. Average monthly temperatures in Yakutsk range from -36.9 C in January to +19.9 C in July. Yakutsk is the largest city built on continuous permafrost, and many houses there are built on concrete piles. The lowest temperatures ever recorded on Earth outside Antarctica and Greenland have occurred in the basin of the Yana River to the northeast of Yakutsk. Winters are extremely cold and long. Summers are sunny, warm and occasionally hot (though short), with daily maximum temperatures exceeding +30 C. The lowest temperature recorded in Yakutsk was -64.4 C on February 5, 1891, and the highest temperatures +38.4 C on , 2011, and +38.3 C on , 1942. The hottest month in records going back to 1834 has been July 1894, with a mean of +23.2 C, and the coldest, January 1900, which averaged −51.4 C. Yakutsk is the largest city in the world with an average winter temperature of below -30 C. Yakutsk is an inland location, being almost 1000 km from the Pacific Ocean, which, coupled with the high latitude, means exposure to severe winters and lack of temperature moderation. July temperatures soar to an above-normal average for this latitude, with the average being several degrees hotter than more southerly Far East cities such as Vladivostok or Yuzhno-Sakhalinsk. The July daytime temperatures are even hotter than some maritime subtropical areas. The warm summers ensure that Yakutsk, despite its freezing winters, is far south of the tree line. The climate is quite dry, with most of the annual precipitation occurring in the summer months, due to the intense Siberian High forming around the very cold continental air during the winter. However, summer precipitation is not heavy since the moist southeasterly winds from the Pacific Ocean lose their moisture over the coastal mountains well before reaching the Lena Valley. The primary economic activity stems from mining activities in the region, particularly coal, gold, and diamonds, with multiple mining companies having set up their headquarters in the city. Precious stones and metals, particularly diamonds, as well as coal, are Yakutsk's major exports. The export volume was $5.55 billion in 2021, making it the 16th largest out of e
