Chandīgarh's air quality reflects the flat Punjab-Haryana foothills at 321 metres at the Shivalik Hills base, with vehicle traffic on surrounding roads and the government, services, and university corridor contributing local sources. The dry winter northwest monsoon concentrates emissions, while the Shivalik Hills provide limited topographic variation and Chandigarh's planned city character with extensive green space generally maintains among India's more moderate planned capital city environments throughout most of the year.

Frequently Asked Questions
Is air quality bad in Chandīgarh right now?
On 9 August 2026, overall air quality in Chandīgarh is poor. AQI is the main air quality indicator at 69.5/100. Pollution peaks around 1:30 PM (O3: 69.5/100).
Will air quality be worse tomorrow in Chandīgarh?

When is air pollution at its worst in Chandīgarh?
In Chandīgarh, vehicle traffic is the main local source, with conditions worsening when the monsoon rains ease off. Rainfall through the monsoon usually keeps levels in check. Outside the monsoon, dry-season stagnation can let pollution build up further.
Are air quality levels in Chandīgarh 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.
