Chandigarh air quality worsens, surpasses Delhi amid dense fog

On the night between Wednesday and Thursday, dense fog blanketed Chandigarh, causing the city’s Air Quality Index (AQI) to rise higher than Delhi's. According to the Central Pollution Control Board (CPCB), Chandigarh recorded an AQI of 319, while Delhi’s AQI stood at 302. Both cities fall into the “very poor” category.

IMD officials reported that the fog trapped pollutants close to the ground, worsening the air quality. Southern parts of Chandigarh were most affected, with Sector 53 recording an AQI of 333, Sector 25 at 323, and Sector 22 at 316 by 6 pm on Thursday. This level of pollution can cause serious health problems, especially for those exposed for long periods.

Fog and weather changes

The India Meteorological Department (IMD) stated that the foggy weather is likely to persist until next week, keeping pollution levels high. A Western Disturbance, expected around January 21, may bring rain that could help clear the air.

Temperatures in Chandigarh dropped on Thursday, with the maximum temperature recorded at 17.8°C, compared to 21.7°C the previous day. Rainfall was minimal, measuring 0.7 mm, but it slightly improved visibility, which had dropped to 70 metres during the early hours of Thursday.

Flight disruptions and alerts

Dense fog caused significant disruptions at Shaheed Bhagat Singh International Airport. Four flights were cancelled, including three by IndiGo and one by Air India. Additionally, 10 flights were delayed due to poor visibility. The IMD has issued an orange alert for dense fog, advising residents to remain cautious.

While the pollution in Chandigarh has raised concerns, officials are optimistic that the upcoming rain and improved weather conditions will bring some relief.
