Which one is colder, Vladivostok or Yuzhno-Sakhalinsk?

Zhno-Sakhalinsk. Vladivostok is affected by the Siberian cold high pressure during the cold winter. Winter is a cold and long season from the end of November to the end of March, with the lowest temperature reaching -40°C. In Yuzhno-Sakhalinsk, the coldest temperature in winter can reach minus 70 degrees Celsius. It is called the cold pole of the northern hemisphere. In comparison, Yuzhno-Sakhalinsk is even colder. Because Yuzhno-Sakhalinsk is located on an island, close to the sea, and has oceanic climate characteristics, the annual temperature range is much smaller than the temperate monsoon climate zone in Northeast China, so the temperature is very low.
