Tianjin's air quality reflects the North China Plain's flat Bohai Sea coastal position adjacent to Beijing, with vehicle traffic on the G2 expressway and surrounding port, petrochemical, and heavy industrial corridor generating elevated industrial SO₂ and PM2.5. Bohai Sea breezes provide limited maritime ventilation, while the Beijing-Tianjin-Hebei regional industrial background and winter anticyclonic inversions maintain Tianjin among North China's more persistently industrially challenged coastal metropolitan environments throughout the year.

Frequently Asked Questions
Is air quality bad in Tianjin right now?
On 10 August 2026, overall air quality in Tianjin is poor. AQI is the main air quality indicator at 64.4/100. Pollution peaks around 3:00 PM (O3: 64.4/100).
Will air quality be worse tomorrow in Tianjin?
On 11 August 2026, air quality conditions in Tianjin will be better than today, with PM1 forecast at fair at 27.1/100. Pollution peaks around 1:00 AM (NO2: 41.8/100).
When is air pollution at its worst in Tianjin?
Air quality in Tianjin tends to be worse when traffic on the surrounding roads and petrochemical and refining operations build up and windblown dust events occur. Dust carried on these winds adds substantially to particulate levels. Sea breezes typically keep conditions in check, except during still weather.
Are air quality levels in Tianjin 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.
