In Yaktusk and Oymyakon in Russia, temperatures regularly dip to -50 degrees Celsius.
If you think it's a bit nippy in the UK, you've never experienced cold like this - a recent thermometer reading in the region clocked in at -62 Celsius, breaking in the process.
The Siberian Times meanwhile, reports that local residents have seen temperatures as low as -67 Celsius in some areas.
As the video at the top of this article shows, some Asian tourists also decided to take a brief bath in the thermal springs, during the cold snap.
We wrote about the area last year, noting the photography of Amos Chapple, from New Zealand.
Here are some of his best shots:
