Delhi AQI Today

Out of the 59 monitoring stations that recorded data across Delhi, 12 registered air quality in the 'severe' category, while 22 logged in the 'very poor' category. Jahangirpuri registered the worst AQI at 463.

According to the Central Pollution Control Board (CPCB) standards, an AQI between 0 and 50 is classified as 'good', 51 to 100 as 'satisfactory', 101 to 200 as 'moderate', 201 to 300 as 'poor', 301 to 400 as 'very poor', and 401 to 500 as 'severe'.

AQI To Turn 'Severe' Tomorrow

According to the Air Quality Early Warning System (EWS), Delhi's air quality is expected to enter the 'severe' category on Monday, November 9, and remain elevated for several days.

Weather experts attribute the anticipated rise in pollution levels to a combination of Diwali-related celebrations, vehicular emissions, peak period of stubble burning in neighbouring states, and unfavourable weather conditions.

Unfavorable weather is further compounding the problem. According to the EWS, a ventilation index below 6,000 square meters per second and average wind speeds under 10 km/h are preventing the dispersion of pollutants.
