Chandigarh's air quality remained in the satisfactory range during this year's Diwali celebrations, marking a notable improvement compared to previous festive seasons. The Central Pollution Control Committee (CPCC) noted that air quality indices stayed within acceptable parameters in the lead-up to the permitted firecracker bursting window of 8 pm to 10 pm on November 8.

The maintenance of satisfactory air quality levels during the festival period reflects efforts to balance residents' celebration traditions with environmental concerns. City authorities had designated specific timeframes for firecracker use, a measure aimed at mitigating air pollution spikes that typically accompany Diwali festivities across northern India.

Metereological factors and wind patterns in the region contributed to better air dispersion during the celebration period. The improvement in air quality metrics suggests that coordinated efforts between regulatory bodies and public compliance with pollution control guidelines have yielded measurable results.

As Indian cities grapple with seasonal air quality degradation, Chandigarh's performance during Diwali offers insights into how regulated festive practices can help maintain environmental standards. The city's experience may serve as a reference point for other urban centers managing the challenge of preserving air quality while accommodating cultural celebrations.
