A devastating heatwave is scorching Siberia and Mongolia, smashing hundreds of temperature records with extraordinary margins. Temperatures soaring near and above 40°C and record-breaking hot nights are pushing these cold-climate regions into unprecedented territory, signaling alarming shifts in the Arctic and Central Asian climate.
🌡️ Daytime inferno and all-time monthly records
- 39.3°C recorded in Chadan, Siberia, close to the historic 40°C mark
- 38.0°C in Ulan Gom, Mongolia
- 37.1°C Turan, Russia
- A blazing 37.0°C in Tanguj, Russia, marking an all-time record for any month
- 36.2°C in Toora Hem, Russia
- 35.4°C in Zima, Russia
These scorching daytime highs at elevation levels of ~1000 meters asl defy expectations, and in some cases break all-month records.
🌙 Nights offer no relief — historic minimum temperatures shattered
The overnight temperatures remain dangerously elevated, intensifying the stress on humans and ecosystems:
- 23.3°C minimum in Lebyazh, Russia — a new record high Tmin
- 21.9°C in Pervomajskoe
- 21.3°C in Tomsk and Toguchin
- 20.8°C in Zalesovo
- 20.6°C minimum at Mutoraj (61°N), Russia, an all-time minimum record
- 18.5°C in Gorin, Russia
These hot nights prevent any meaningful cooling, increasing health risks and ecological strain.
🌍 Impacts and implications
This historic heatwave accelerates permafrost thaw, increasing greenhouse gas emissions and wildfire risk across Siberia and Mongolia. The boreal forests face unprecedented heat stress, and local communities must endure extreme, potentially dangerous heat in regions unaccustomed to such conditions.
These extremes illustrate the rapid Arctic amplification and climate shifts occurring now — a troubling glimpse into a warming future.
