Introduction
Delhi spent Diwali breathing some of the dirtiest air of the year. The capital's average air quality index (AQI) stood at 376 on Sunday, 8 November 2026, in the "very poor" category, as smog cut visibility across the city and 19 of its 59 monitoring stations slipped into the "severe" zone.
It came despite Stage III restrictions under the Graded Response Action Plan (GRAP), in force since 6 November. Forecasters expect severe air from Monday, 9 November, for several days.
What Happened?
Data from the Central Pollution Control Board (CPCB) put Delhi's daily average AQI at 376 on Sunday, up from 369 on Saturday. By 7 pm, 19 of the 59 stations reporting data were severe, 33 were very poor and seven were poor. Jahangirpuri recorded the worst reading at 460, with Rohini, North Campus and Bawana all above 440.
Saturday had already set an unwelcome record: the 24-hour average of 369 at 4 pm was the worst Diwali-eve reading in 10 years, the highest since 2016, when it was 404. Firecracker smoke, vehicle emissions and farm-fire smoke pushed the city to the edge of the severe threshold of 400. ISRO's INSAT-3DS satellite detected 415 fire pixels across the two states on Saturday, about 5.5 times the 1 November count.
Why Does This Matter?
An AQI of 376 is not an abstract number. On the CPCB scale, 301 to 400 is "very poor" and can cause respiratory illness on prolonged exposure; above 400, in the "severe" band, it can affect even healthy people and seriously aggravate heart and lung conditions.
Children, older people and anyone with asthma or heart disease are the most exposed, and the risk carries into the working week, when millions of commuters will spend hours in the same air.
Important Details
Delhi average AQI on Diwali: 376, "very poor", up from 369 on Saturday.
Stations severe at 7 pm: 19 of 59; 33 more very poor. Worst: Jahangirpuri 460.
Worst Diwali eve in 10 years: Saturday's 369, highest since 2016 (404).
Forecast: severe from Monday, 9 November, for a few days; the Indian Institute of Tropical Meteorology projects 406 by 4 am Monday.
Restrictions: GRAP Stage III in force across Delhi-NCR since 6 November.
Farm fires: 415 fire pixels across Punjab and Haryana on Saturday, about 5.5 times the 1 November count.
Background and Context
Delhi's air turns toxic every winter: falling temperatures trap pollutants near the ground, farm fires add smoke, vehicles and construction add dust and exhaust, and Diwali firecrackers deliver a sharp spike on top. The city entered the festival with GRAP Stage III in force and a firecracker ban allowing only green crackers under Supreme Court orders, yet Saturday's Diwali-eve reading was the worst in a decade.
What Happens Next?
The outlook is poor. The Early Warning System expects severe air from Monday, 9 November, for a few days, as Diwali emissions combine with vehicle pollution and peak stubble burning. The Indian Institute of Tropical Meteorology projects 406 by 4 am on Monday, and the Commission for Air Quality Management can escalate to Stage IV, with stricter curbs including on vehicle entry, if readings stay severe.
What Readers Should Know
Check your area's AQI before stepping out on Monday; readings vary widely.
Stay indoors while the air is severe and keep windows shut; wear a well-fitted N95 mask outside.
Children, older people and anyone with asthma or a heart condition should avoid morning walks and outdoor exercise.
Seek medical advice for breathing difficulty or chest pain rather than waiting for the air to clear.
FAQs
Is an AQI of 376 dangerous? Yes. On the CPCB scale, 301 to 400 is "very poor" and can cause respiratory illness on prolonged exposure. Even healthy people may feel irritation, and people with lung or heart conditions face a serious risk.
When will Delhi's air improve? Not soon. The Early Warning System expects severe air from Monday, 9 November, for a few days. Improvement depends on wind picking up and farm-fire smoke easing.
What is GRAP Stage III? Stage III of the Graded Response Action Plan is a set of emergency restrictions imposed when Delhi's AQI turns very poor, including curbs on construction, polluting vehicles and industry. In force since 6 November.
