Beijing has invested billions in improving air quality, and readings have improved substantially over the past decade. However, the city still experiences severe pollution episodes, especially in winter when heating demand rises and inversions trap emissions. Dust storms from the Gobi Desert add a seasonal PM10 challenge.
Beijing's AQI varies widely, from Good (20-50) on clean days to Hazardous (300+) during severe winter pollution episodes. Annual average PM2.5 has been declining but remains above WHO guidelines.
Autumn (September-October) typically offers the best running conditions with blue skies and lower pollution. Always check the AQI before running, and keep an indoor backup plan ready for high-pollution days.
