Key Takeaways
Delhi's average air quality index (AQI) stood at 368 at 7 am on Monday, in the 'very poor' range, with 15 monitoring stations recording 'severe' readings above 400.
Sonia Vihar was worst at 449, followed by Burari Crossing at 445 and Vivek Vihar at 441, CPCB data showed.
Stage III of the Graded Response Action Plan (GRAP) remains in force across Delhi-NCR, with schools up to Class 5 in hybrid mode and older diesel and petrol vehicles barred.
Introduction
Delhi woke on Monday to a thick blanket of smog, a day after Diwali, as the city's air quality stayed in the 'very poor' range and 15 monitoring stations crossed into 'severe'. The Central Pollution Control Board (CPCB) put the capital's average air quality index (AQI) at 368 at 7 am, with the worst station reading, 449 at Sonia Vihar, close to the top of the scale. Forecasters expect severe air to persist over the coming days.
What Happened?
The smog set in overnight as residents burst firecrackers well beyond the 10 pm deadline prescribed by the Supreme Court. Data from the Delhi Pollution Control Committee showed PM2.5 levels at Akshardham reaching 760.99 micrograms per cubic metre at 11 pm on Sunday.
By Monday morning, visibility had dropped sharply in parts of the city, including Inderlok. Of the 54 monitoring stations reporting valid data, all recorded AQI levels above 200, and 50 registered readings above 300. A private tracker, AQI.in, recorded a far higher overnight peak of 1,331 at 1.31 am, though its methodology differs from the CPCB's official index.
Delhi's daily average AQI stood at 376 on Sunday, compared with 369 on Saturday, both in the 'very poor' category. The morning's readings confirm the pre-festival forecast: the Air Quality Early Warning System had warned that the capital's air could deteriorate to 'severe' from 9 November and remain there for the following few days.
Why Does This Matter?
More than 30 million people live in Delhi-NCR, and the post-Diwali spike lands at the start of the winter pollution season, when low wind speeds and falling temperatures trap pollutants close to the ground. PM2.5, the fine particulate matter driving the current readings, penetrates deep into the lungs, with children, the elderly and people with existing lung conditions most at risk.
The timing also matters for policy. The Commission for Air Quality Management (CAQM) invoked GRAP Stage III on Friday, 6 November, as a preventive step. That the city still woke to 15 severe stations shows the limits of emergency curbs when festival emissions combine with seasonal conditions.

Station readings change through the day, so figures from different times of the morning vary slightly. The ITO station had already recorded 406 at 4.20 am, according to ANI. Under the CPCB's classification, an AQI of 301 to 400 is 'very poor' and 401 to 500 is 'severe'.
GRAP Stage III, in force since 6 November, bans dust-generating construction and demolition work across Delhi-NCR, bars BS-III petrol and BS-IV diesel vehicles from Delhi, and requires schools up to Class 5 to run in hybrid mode. The curbs also apply in Noida, Ghaziabad, Faridabad, Gurugram and Sonipat.
Background and Context
Delhi's air turns toxic almost every winter. Stubble burning in neighbouring states, vehicle exhaust, construction dust and local emissions combine with cold, still air that prevents pollutants from dispersing, and Diwali firecrackers add a concentrated overnight burst on top of that seasonal base.
The GRAP framework has four stages, from dust control in Stage I to vehicle restrictions and a construction halt in Stage III, and heavy-vehicle restrictions in Stage IV for air above 450.
What Happens Next?
The Air Quality Early Warning System expects Delhi's air to stay 'severe' over the coming days and to fluctuate between 'very poor' and 'severe' over the following six days. The CAQM reviews GRAP measures against the forecast, and Stage IV curbs become possible if the average AQI stays above 450.
What Readers Should Know
Avoid strenuous outdoor exercise in the early morning, when pollution is at its worst, and keep windows shut until the smog lifts later in the day.
Wear a well-fitted N95 mask outdoors, and consider an air purifier indoors.
Children, elderly people and anyone with asthma or heart conditions should limit time outdoors.
Check live readings on the CPCB's Sameer app before planning travel; schools up to Class 5 are running in hybrid mode.
FAQs
What is Delhi's AQI today?
Delhi's average AQI stood at 368 at 7 am on Monday, 9 November 2026, in the 'very poor' category. Fifteen stations recorded 'severe' readings above 400, with Sonia Vihar the worst at 449.
What does a 'severe' AQI mean?
Under the CPCB's classification, an AQI of 401 to 500 is 'severe'. At this level, the air can affect healthy people and seriously affect those with heart or lung conditions, who should avoid outdoor physical activity.
Are Delhi schools closed because of the pollution?
No. Schools up to Class 5 have been directed to operate in hybrid mode since 6 November, so pupils can attend either in person or online. There is no fixed end date for the GRAP Stage III curbs; the CAQM lifts them when the AQI improves.
