Delhi's dangerous air pollution shifted from 'severe' to 'very poor' on Tuesday morning, January 20, 2026. The city's average Air Quality Index (AQI) dropped slightly to 395, ending three days of 'severe' pollution. Yet, the air remains troubling across the capital. Data from the CPCB Sameer app shows 23 monitoring stations still reported 'severe' AQI, 14 stayed in 'very poor', and 1 in the 'poor' category. Wazirpur had the worst air quality with an AQI of 445, closely followed by Anand Vihar at 444 and Jahangirpuri at 443. The Central Pollution Control Board (CPCB) classifies AQI from 401 to 500 as 'severe,' 301 to 400 as 'very poor,' and below that as 'poor' or better. Delhi hit 'severe' pollution levels for three straight days—Saturday, Sunday, and Monday—pushing the Commission for Air Quality Management (CAQM) to enforce Stage 4 restrictions. The Air Quality Warning System predicts that pollution will stay in the 'very poor' zone for the next two days. Weather conditions offered limited help, with minimum temperatures mostly around 7 to 9 degrees Celsius and moderate fog expected as the maximum temperature climbs to 24 degrees Celsius.
