Pollution and Air Quality in China in 2026: What Visitors Actually Face
China's air quality has improved substantially since 2013, but pollution remains a real consideration in some cities and seasons. This guide explains PM2.5, AQI readings, masks, and which cities and months to watch.
China's air quality has improved substantially since 2013. Beijing's annual PM2.5 average fell from over 80 μg/m³ in 2013 to around 30 μg/m³ by 2024, due to coal-to-gas conversions, heavy industry relocation, and stricter vehicle emissions standards.
Areas still worth watching: north China plain cities (Shijiazhuang, Baoding) remain problematic. Beijing in winter (November–February) still sees haze events. Chengdu, Chongqing, and Xi'an — surrounded by mountains — trap pollution during wind-still periods. Cities with generally cleaner air: Shanghai, Guangzhou, Shenzhen, Kunming, and Hainan.
AQI practical guide: 0–100 fine, 101–150 sensitive individuals should limit outdoor exercise, 151–200 wear a mask, 200+ avoid prolonged outdoor exposure. Use AQI China, IQAir, or Windy apps for real-time readings. N95/KN95 masks (¥3–10 each at pharmacies) are effective; surgical masks are not tight enough to filter PM2.5.
Plan Beijing, Xi'an, and Chengdu visits for spring (March–May) or autumn (September–October) for the most reliable air quality.
