Delhi saw a slight uptick in air quality on Monday after several days in the “severe” zone, though pollution levels stayed firmly in the “very poor” category as a dense layer of smog blanketed the city.

Residents woke to heavy haze, with the Air Quality Index (AQI) exceeding 350 at most Central Pollution Control Board (CPCB) monitoring stations. Some pockets continued to record “severe” pollution.

At 8 a.m., Ashok Vihar logged an AQI of 382, while ITO reported 392, Rohini 404 and Punjabi Bagh 383. Under CPCB norms, an AQI reading of 301–400 is classified as “very poor” and 401–500 as “severe”.

Delhi’s 24-hour average AQI stood at 377 at 4 p.m. on Sunday. CPCB data showed 18 stations recording “severe” air quality and 20 stations reporting “very poor” levels.
