With an extreme subarctic climate, Oymyakon is known as one of the candidates for the Northern Pole of Cold, the other being the town of Verkhoyansk. The ground there is permanently frozen (continuous permafrost). In 1924 a temperature of −71.2°C was recorded, and is currently the lowest temperature ever recorded in a habitat center.
