Introduction
The most extreme temperature ranges are found in continental interiors far from the moderating influence of oceans. Central Siberia and northern Canada hold most of the records.
These locations experience punishing cold in winter and surprisingly hot summers. The annual temperature swing can exceed 100°C.
1. Verkhoyansk, Russia
- Record Low: -67.8°C (-90°F)
- Record High: +37.3°C (+99°F)
- Range: 105.1°C
Verkhoyansk holds the record for the greatest temperature range at any settlement on Earth. The 105°C swing from coldest to hottest is almost inconceivable.
In winter, exhaled breath instantly freezes and falls as tiny ice crystals called "the whisper of stars."
2. Yakutsk, Russia
- Record Low: -64.4°C (-84°F)
- Record High: +38.4°C (+101°F)
- Range: 102.8°C
Yakutsk is the coldest major city on Earth and yet has hot summers. Cars must be left running all winter or kept in heated garages, or the engines will freeze solid.
3. Oymyakon, Russia
- Record Low: -71.2°C (-96°F)
- Record High: +34.6°C (+94°F)
- Range: 105.8°C
Oymyakon competes with Verkhoyansk for the title of coldest inhabited place. About 500 people live here permanently, where glasses can freeze to your face in winter.
4. Fort Vermilion, Canada
- Record Low: -61.1°C (-78°F)
- Record High: +39.4°C (+103°F)
- Range: 100.5°C
Fort Vermilion has the largest temperature range in North America. This remote Alberta community experiences extreme cold from Arctic air masses and surprising summer heat.
5. Snag, Yukon, Canada
- Record Low: -63°C (-81.4°F)
- Record High: +36°C (+97°F)
- Range: 99°C
Snag holds the record for the coldest temperature ever recorded in North America (-63°C in 1947). The reading was so extreme that the mercury thermometer could barely function.
6. Ulaanbaatar, Mongolia
- Record Low: -49°C (-56°F)
- Record High: +39°C (+102°F)
- Range: 88°C
Ulaanbaatar is the coldest national capital on Earth. Half the city's residents still live in traditional gers (yurts) and burn coal for heat, creating severe winter air pollution.
7. International Falls, Minnesota, USA
- Record Low: -48°C (-55°F)
- Record High: +40°C (+104°F)
- Nickname: Icebox of the Nation
International Falls trademarked the nickname "Icebox of the Nation." Its temperature range of 88°C is the largest of any city in the contiguous United States.
8. Astana (Nur-Sultan), Kazakhstan
- Record Low: -51.6°C (-61°F)
- Record High: +42°C (+108°F)
- Range: 93.6°C
Astana is the second coldest national capital after Ulaanbaatar. The city was purpose-built on the open steppe, fully exposed to Siberian winter winds.
Key Facts
- Verkhoyansk and Oymyakon both have temperature ranges exceeding 105°C.
- Continental interiors have the most extreme ranges because oceans aren't there to moderate temperatures.
- Yakutsk is the coldest major city on Earth with 300,000+ residents.
- Fort Vermilion has the largest range in North America at 100.5°C.
- Several of these locations have permanently frozen ground despite hot summers.
Fun Facts
- In Yakutsk, people leave their cars running 24/7 in winter because a turned-off engine freezes solid.
- Oymyakon is so cold that glasses freeze to people's faces and must be pulled off carefully.
- In Verkhoyansk, frozen breath creates ice crystals called "the whisper of stars."
- International Falls, Minnesota sued a neighboring city for using the "Icebox" nickname.
Final Thoughts
Places with the most extreme temperature ranges experience conditions that seem impossible side by side. These locations remind us that our planet's climate is capable of extraordinary extremes within a single community.
