Using data from the World Bank, which offers reliable, country‑specific climate metrics, we examine average annual temperatures from 2012 to 2022.
While some rankings may appear obvious, others can be surprising, and the order is not always what you’d anticipate.
Canada’s extensive tundra and boreal forests, coupled with its proximity to the Arctic Circle, create long, brutally cold winters that pull the country’s average temperature down to the lowest in the world.
Russia, unsurprisingly, ranks second. The icy expanse of Siberia produces intensely frigid winters, and even the southern, western regions remain chilly due to higher elevations.
Mongolia, situated between China and Russia, sits at the third spot. Its average temperature hovers just above freezing, with persistent winter lows and high‑elevation mountainous terrain amplifying the cold.
True to its name, Iceland experiences harsh winters, heavy snowfall, and ice. Although classified as subarctic, the Gulf Stream moderates temperatures slightly.
Scandinavia’s northernmost nation, Norway, boasts the most dramatic winter lows in Northern Europe, especially in its far‑north regions where temperatures plunge far below freezing.
Finland’s neighboring country also endures extremely cold winters, with lows reaching –30 °C (22 °F). The north is the coldest, but even the south experiences frigid conditions. Its historical average, slightly lower than Finland’s, places it here.
Central Asian Kyrgyzstan shows wide temperature variation due to its varied topography. While low‑lying areas can be hot in summer, the high‑elevation north is buffeted by cold winds and very low winter temperatures.
Sweden, another Scandinavian nation, shares severe winter conditions with its neighbors. Its temperate continental climate is tempered by high‑latitude northern regions that experience seriously cold temperatures.
Bordering Kyrgyzstan, Tajikistan’s climate is highly variable. While some areas can exceed 104 °F (40 °C) in summer, the Pamir Mountains drop to –58 °F (–50 °C) in winter.
Across the Baltic Sea from Sweden and Finland, Estonia enjoys a milder climate. Its relatively high latitude is offset by Atlantic currents that bring warmer air inland, placing it lower on the list.
