On December 6, 2025, Delhi awoke to hazardous air conditions as smog enveloped the city, pushing the overall AQI to 333. This reading indicates very poor air quality, according to data from the Central Pollution Control Board (CPCB).
The city's 39 monitoring stations provided a grim snapshot: 35 stations logged AQI levels in the very poor range (301-400), while the remaining four fell into the poor category (201-300). This widespread pollution is exacerbated by a cold wave, trapping emissions from vehicles and other sources close to the ground.
Keywords associated with the event highlight contributing factors such as vehicular emissions and the implementation of Graded Response Action Plan (GRAP) measures for pollution control in the National Capital Region (NCR). The combination of winter weather and ongoing emissions has intensified the smog, affecting daily life in Delhi during December.
