Field notes
Subarctic continental — among the coldest capital cities in the world. January averages -22°C with regular drops to -35°C; daily highs barely reach -10°C through the deep winter. Summer (June–August, 14–17°C average) is short and pleasant but with low humidity and high UV at altitude. Spring (April–May) is rapid and dusty; autumn (September) is the cleanest shoulder window. The structural problem in winter is air quality — coal-burning ger districts produce some of the worst PM2.5 readings on the planet (often AQI 400+ for weeks at a time).
