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.

Will air quality be worse tomorrow in Yiwu?
On 11 August 2026, air quality conditions in Yiwu will be worse than today, with AQI forecast at poor at 62.7/100. Pollution peaks around 12:00 PM (O3: 62.7/100).
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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
