Pole of Cold

• 1. Antarctic Extremes At Vostok

  ›

  On the 21st of July 1983, the Russian Antarctic station Vostok recorded a temperature of minus 89.2 degrees Celsius. This remains the lowest naturally occurring temperature ever measured on Earth. The station sits at an elevation of 3,488 meters above sea level. It lies more than 1,500 kilometers from the nearest ocean coast. Almost three months of civil polar night occur every year between early May and late July. These geographic factors combine to create an environment where summer temperatures rarely rise above minus 60 degrees Celsius. Winter temperatures frequently fall below minus 70 degrees Celsius. By comparison, the South Pole is warmer by about 5 degrees Celsius on average due to its lower elevation. The lowest temperature ever recorded at the South Pole was minus 82.8 degrees Celsius.

• 2. Satellite Discovery Of Dome A

  ›

  Prior to 1995, Vostok stood as the only research station on the Antarctic Plateau above 3,000 meters in elevation. No other stations existed for several hundred kilometers in any direction. Temperatures below minus 80 degrees Celsius would have gone unrecorded if they occurred elsewhere. An automatic weather station installed at Dome A in 2005 recorded minus 93.2 degrees Celsius as its coldest reading so far in 2010. Satellite measurements taken between 2010 and 2013 revealed even colder spots along a ridge between Dome A and Dome F. These satellite readings showed temperatures reaching minus 98.2 degrees Celsius. The lowest reliable temperature detected was minus 93.2 degrees Celsius recorded in 2010. This extreme cold occurs in hollows slightly below the peak of the ice ridge where trapped air flows downhill. Similar low ranges appeared across multiple sites along the ridge over several years suggesting this may be the limit achievable under local atmospheric conditions.

• 3. Siberian Towns Compete For Title

  ›

  Two towns in Sakha, Russia compete for the title of Northern Hemisphere Pole of Cold. Verkhoyansk sits at an altitude of 105 meters while Oymyakon rises to 644 meters. Ivan Khudyakov discovered the Northern Pole of Cold in December 1868 by measuring minus 67.8 degrees Celsius in Verkhoyansk. Sergey Kovalik registered minus 67.8 degrees Celsius there on the 15th of January 1885. That measurement was published in the Annals of the General Physical Observatory in 1892 but contained a printing error listing it as minus 67.8 instead of minus 67.8. One can still find this incorrect value in some literature today. The coldest reliably measured temperature in Verkhoyansk reached minus 67.8 degrees Celsius on February 5 and 7 of 1892. On the 6th of February 1933, Oymyakon's weather station recorded minus 67.7 degrees Celsius making it the coldest reliably measured temperature for the Northern Hemisphere at that time. The station sits in a valley between Oymyakon and Tomtor surrounded by mountains reaching 1,000 meters causing cold air to pool below.

• 4. Greenland Ice Sheet Record Validated

  ›

  The World Meteorological Organization recognized a new record in 2020 for the lowest temperature in the Northern Hemisphere. This reading came from near the topographic summit of the Greenland Ice Sheet on the 22nd of December 1991. An automatic weather station known as Klinck AWS recorded minus 69.6 degrees Celsius at an altitude of 2,448 meters. The WMO validated metadata and observations confirming instrument calibration and monitoring procedures were sound. They accepted the observation as officially the lowest observed near-surface air temperature for both the Northern and Western Hemispheres. This measurement remained hidden for nearly 30 years before being uncovered. It surpassed previous records held by Siberian towns despite their long history of extreme cold measurements.

• 5. Historical Measurement Errors And Corrections

  ›

  Early 19th-century recording mistakes regarding Siberian temperatures persisted in literature for decades. Sergey Kovalik's the 15th of January 1885 measurement was published with a typo listing minus 67.8 instead of minus 67.8. That error appeared in the Annals of the General Physical Observatory in 1892. One can still find this incorrect value in some modern literature today. These early errors complicated efforts to determine which location truly holds the coldest title. Reliable measurements required careful instrument calibration and consistent monitoring over time. The correction process took many years to resolve discrepancies between different stations and publications.

• 6. Climate Change Impact On Cold Zones

  ›

  The average temperature in Oymyakon has risen about 2.7 degrees Celsius since preindustrial times. Recent studies show that winter temperatures in the area increase with elevation by as much as 1 degree per kilometer. This warming trend affects how cold air pools within valleys surrounding the weather station. Glaciers in the Suntar-Khayata Range have responded to these changing conditions. Rising temperatures alter the stability of previously frozen ground and affect local ecosystems. Despite historical extremes, current data shows clear shifts toward warmer averages compared to past centuries. Scientists monitor these changes to understand broader climate patterns affecting polar regions globally.
