Xiamen's air quality benefits from its exceptional Fujian coastal island position on the Taiwan Strait, with consistent Taiwan Strait and South China Sea breezes providing reliable and often powerful maritime ventilation. Vehicle traffic on surrounding expressways and the electronics, logistics, and tourism corridor contribute local sources, while the outstanding island coastal exposure and the warm maritime climate generally maintain Xiamen among southeastern China's cleaner major coastal cities throughout most of the year.

Frequently Asked Questions
Is air quality bad in Xiamen right now?
On 10 August 2026, overall air quality in Xiamen is poor. AQI is the main air quality indicator at 61.0/100. Pollution peaks around 7:00 PM (NO2: 61.0/100).
Will air quality be worse tomorrow in Xiamen?
On 11 August 2026, air quality conditions in Xiamen will be similar to today, with AQI forecast at poor at 76.4/100. Pollution peaks around 3:00 PM (O3: 76.4/100).
When is air pollution at its worst in Xiamen?
Pollution in Xiamen typically rises when traffic on the surrounding roads, textile and manufacturing operations, together with seasonal tourism traffic combine, especially once the sea breeze weakens. Sea breezes typically keep conditions in check, except during still weather. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Xiamen 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.
