Chandigarh Chokes: Air Quality Remains Poor Amidst Fog

Chandigarh has been experiencing "poor" air quality for three consecutive days as of December 19, 2025, with the Air Quality Index (AQI) remaining elevated due to prevailing weather conditions. Dense fog and cold temperatures are preventing the dispersion of pollutants, trapping them close to the ground. This situation is exacerbated by the absence of rainfall since October, as western disturbances have been inactive in the region.

Experts highlight that the lack of solar penetration and moisture in the air, combined with trapped pollutants, contribute to the persistently poor AQI. While the fog has reportedly become lighter, a significant improvement in air quality is expected only once these foggy conditions clear. Forecasts indicate partly cloudy skies for the next few days, with no rainfall predicted, meaning pollution levels may continue to be a concern.
