Delhi Chokes Under Toxic Smog as Air Quality Hits Severe Levels
13 Nov
Summary
- Air quality index reaches 644, over 26 times WHO limit
- Schools closed, hybrid mode ordered for higher grades
- Stubble burning contributes 10% to Delhi's pollution

On November 13, 2025, the national capital of India, Delhi, continues to choke under a thick layer of smog, with air quality plunging to 'severe' levels. The Air Quality Index (AQI) has reached an alarming 644, far exceeding the World Health Organization's (WHO) recommended limit of 15 µg/m³ for PM2.5 levels.
In response to the worsening air quality, the Commission for Air Quality Management (CAQM) has implemented Stage III of the Graded Response Action Plan (GRAP) across Delhi-NCR. The Delhi government has also ordered the closure of schools up to Class V and instructed all government, private, and unaided institutions to shift to hybrid mode for higher grades.
Satellite data shows that stubble burning in neighboring states is contributing about 10.1% to Delhi's PM2.5 levels, while transport emissions are likely to rise marginally to 19.3%. Experts have urged residents to take precautions, such as avoiding outdoor exercise during peak pollution hours, wearing N95 masks, and using air purifiers indoors to reduce exposure to fine particulate matter.
