Delhi Air Quality Index slips near “severe” mark as a thick layer: A practical reader guide

Despite stringent restrictions on fireworks imposed by the Supreme Court, people defied the deadline way past 10 p.m. on Deepavali night.

Delhi Air Quality Index slips near “severe” mark as a thick layer of toxic haze engulfed India’s National capital on Monday (November 9, 2026).

Beyond the National Capital, AQI also slumped in several other Indian cities. Mumbai saw hazy conditions, with a thick layer of smog blanketing the Kalanagar and Bandra areas as air quality worsened. In Uttar Pradesh, a thick layer of smog blanketed Lucknow as several parts of the city woke up to hazy conditions. With Stage III measures in force following the CAQM’s decision, existing restrictions will continue alongside additional pollution-control measures, increased enforcement and directions to concerned agencies to prevent further deterioration in air quality. The emergency action plan applies across Delhi and adjoining districts of Haryana, Uttar Pradesh and Rajasthan. It is invoked as a precautionary measure based on meteorological and pollution forecasts provided by the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), allowing restrictions to be implemented before citywide AQI levels reach the ‘severe’ category. GRAP is a four-stage emergency framework managed by the CAQM in coordination with the CPCB and regional state governments. Restrictions become progressively stricter as air quality deteriorates.

Delhi AQI levels have gone up to 404 at 4 a.m. today and have been in respite since then, according to the Central Pollution Control Board Live Dashboard. Burari Crossing registered the highest reading at 441, followed by Vivek Vihar at 437, Delhi Technological University (DTU) at 434, North Campus of Delhi University and Jahangirpuri at 433 each, and Rohini at 430.

Central and industrial belts similarly saw a spike in readings, including Nagpur (239), Pune (221), Bhopal (205), Mumbai (171) and Kolkata (167), exacerbated by Deepavali emissions. An AQI between 0 and 50 is considered ‘good’, 51-100 ‘satisfactory’, 101-200 ‘moderate’, 201-300 ‘poor’, 301-400 ‘very poor’ and 401-500 ‘severe’, according to CPCB classification.

Meanwhile, southern cities maintained relatively cleaner profiles, with Chennai standing at 208 (”poor”), while Bangalore (127), Hyderabad (120) and Thiruvananthapuram (67) recorded moderate-to-satisfactory air quality levels.
