Suzhou in Jiangsu reflects the Yangtze delta's flat canal and lake district adjacent to Shanghai, with vehicle traffic on surrounding expressways and the semiconductor manufacturing, technology, and precision engineering corridor generating elevated industrial PM2.5. East China Sea breezes provide limited maritime ventilation, while winter anticyclonic inversions concentrate industrial and heating emissions and Suzhou generally maintains moderate to elevated Yangtze Delta technology industrial corridor readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Suzhou right now?
On 16 July 2026, overall air quality in Suzhou is poor. AQI is the main air quality indicator at 78.1/100. Pollution peaks around 1:00 PM (O3: 78.1/100).
Will air quality be worse tomorrow in Suzhou?
On 17 July 2026, air quality conditions in Suzhou will be worse than today, with AQI forecast at very poor at 81.3/100. Pollution peaks around 4:00 PM (O3: 81.3/100).
When is air pollution at its worst in Suzhou?
In Suzhou, vehicle traffic along with textile and manufacturing operations are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Suzhou based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
