Delhi-NCR Shrouded in Hazardous Smog as Air Quality Deteriorates
9 Nov
Summary
- Air Quality Index reaches 'severe' levels in parts of Delhi-NCR
- 24 out of 39 monitoring stations record AQI above 400
- Experts warn of increased health risks, advise limiting outdoor activities
As of November 9th, 2025, the Delhi-NCR region has been shrouded in a dense, hazardous smog, with the Air Quality Index (AQI) plummeting to alarming levels. The Central Pollution Control Board (CPCB) reported that the 24-hour average AQI stood at 361, with 24 out of 39 monitoring stations in the region recording AQI levels above 400 - the highest pollution spike of the season so far.
Areas like Rohini (435), Nehru Nagar (426), Bawana (426), RK Puram (422), and ITO (420) were among the worst affected, with the average AQI recorded at 391 in Delhi, 391 in Noida, 366 in Greater Noida, 387 in Ghaziabad, and 252 in Gurugram. The worsening pollution is linked to falling temperatures, which make the air heavier and reduce wind speed, causing pollutants to remain trapped near the surface.
Health experts have advised residents to limit outdoor activities, especially during early mornings and late evenings, wear protective masks, and avoid direct exposure to the polluted air. Prolonged exposure to such poor air quality can significantly increase the risk of lung and respiratory diseases, especially for children, the elderly, and individuals with asthma or heart conditions.
