About air quality in Delhi
This page tracks live PM2.5, PM10, ozone, nitrogen dioxide and the US and Indian (CPCB NAQI) air quality indexes for Delhi, India. Delhi NCR sits in the Indo-Gangetic plain, where winter temperature inversions, low wind speed, vehicle exhaust, construction dust and crop-residue burning in Punjab and Haryana push PM2.5 well above safe limits from late October to January. Air is usually cleanest during the monsoon (July–September). Browse 39 areas of Delhi below to see which parts are currently most polluted.
Values are modelled estimates (CAMS via Open-Meteo, ~10 km grid) and are refreshed hourly. See our methodology.
