Delhi Air Chokes Haze Fog Trap Pollutants AQI Hits Severe

On Thursday morning, the national capital of India, New Delhi, woke to a dense blanket of haze and fog that anchored pollutants near the ground, driving the Air Quality Index (AQI) into the “very poor” range and even “severe” in several hotspots. 

According to the Central Pollution Control Board (CPCB), the city recorded an overall AQI of 357 significantly elevated from the 279 recorded just a day earlier. In several areas such as Akshardham and Anand Vihar, the air quality dipped into the “severe” category, raising immediate health concerns. 

Meteorological conditions played a key part. Calm winds and low ventilation (with the “ventilation index” remaining below 6,000 m²/s) meant pollutants could not disperse. Visibility plummeted the India Meteorological Department (IMD) recorded visibility as low as 1,000 metres at Palam and 800 metres at Safdarjung. 

In practical terms, the deteriorating air quality poses a serious threat, especially for children, the elderly, those with respiratory or cardiac conditions, and outdoor workers. Medical professionals advise limiting outdoor exposure, using masks, and running indoor air-purifiers where possible.

This event is yet another reminder that Delhi’s winter pollution season has returned early and forcefully. Historically, the city’s air quality plunges during October-to-February due to factors like stubble burning in neighbouring states, increased vehicular emissions, construction dust and weather patterns that trap smog. 

For residents and policymakers alike, the message is urgent: without effective mitigation and public awareness, days like this will continue to recur. In the meantime, citizens are advised to check live AQI readings, reduce outdoor exposure, and avoid burning biomass or using fire-crackers small personal steps that can cumulatively help.
