On Tuesday, Delhi witnessed its worst air quality of the season so far, with the AQI plunging to 423.
In response, the Centre activated Stage III of the Graded Response Action Plan (GRAP), enforcing stricter anti-pollution measures across the city.
As per CPCB data on Tuesday, Anand Vihar recorded an AQI of 412, Alipur reported 442, and Bawana registered the highest level at 462. Chandni Chowk recorded an AQI of 416, while RK Puram and Patparganj logged 446 and 438, respectively.
Sonia Vihar also recorded a ‘severe’ AQI of 433, indicating hazardous air conditions across the city.
According to CPCB’s 24-hour average data, the air quality on Monday stood at 362, falling under the ‘Very Poor’ bracket.
As per CPCB norms, an AQI between 0–50 is considered ‘Good’, 51–100 ‘Satisfactory’, 101–200 ‘Moderate’, 201–300 ‘Poor’, 301–400 ‘Very Poor’, and 401–500 ‘Severe’.
Since Diwali, the capital’s air quality has stubbornly remained in the ‘poor’ or ‘very poor’ zone, often slipping into the ‘severe’ range due to a combination of stubble burning, vehicular emissions, and stagnant weather conditions.
The average AQI in Delhi for the period between January 1 and November 9, 2025, has been recorded as 175, which was 189 during the corresponding period last year.
PM2.5 and PM10 concentration levels are 75 ug/m3 and 170 ug/m3, respectively, during this period, as against 87 ug/m3 and 191 ug/m3, respectively, during the corresponding period last year, according to a statement from the Ministry of Environment, Forest and Climate Change.
Meanwhile, the temperatures in Delhi have continued to fall.
On Tuesday, the minimum temperature was recorded at 10.2°C, 4.1 degrees below normal, while the maximum was expected to touch around 28°C.
The city also reported its first cold wave of the season earlier this week, with Aya Nagar recording a chilly 9.9°C on Monday.
