Yiwu's air quality reflects the Zhejiang central Yiwu River valley position, with vehicle traffic on surrounding expressways and the small commodities manufacturing — Yiwu being the world's largest small commodity market — and logistics corridor contributing elevated vehicle and industrial emissions. The surrounding Jinqu basin's topographic variation creates modest concentration, while East China Sea breezes provide limited maritime ventilation and the extraordinary market and logistics activity makes Yiwu Zhejiang's most distinctively trade-defined air quality environment throughout the year.

Frequently Asked Questions

On 16 July 2026, overall air quality in Yiwu is poor. AQI is the main air quality indicator at 75.9/100. Pollution peaks around 2:00 PM (O3: 75.9/100).
Will air quality be worse tomorrow in Yiwu?
On 17 July 2026, air quality conditions in Yiwu will be worse than today, with AQI forecast at very poor at 88.4/100. Pollution peaks around 2:00 PM (O3: 88.4/100).
When is air pollution at its worst in Yiwu?
In Yiwu, traffic emissions along with manufacturing activity 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 Yiwu 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.
