Delhi’s Diwali dawned under a thick layer of smog, as the air quality index (AQI) was recorded at a “very poor” level of 328, according to data from the System of Air Quality and Weather Forecasting and Research (SAFAR). Although measures were in place to curb pollution, the AQI failed to improve, further emphasizing the ongoing air quality challenges faced by the capital and its surrounding areas.
With AQI values between 301 and 400 categorized as “very poor” and values over 400 considered “severe,” residents experienced reduced visibility and a dense haze. Anand Vihar, one of Delhi’s 40 monitoring stations, reported an AQI of 419, falling into the “severe” category. This trend continued across areas including Alipur, Ashok Vihar, Aya Nagar, Dwarka, IGI Airport, Jahangirpuri, Mundka, and Rohini.
According to the Indian Institute of Tropical Meteorology (IITM), Pune, the air quality is projected to remain in the “very poor” category through Thursday and Friday, with potential to shift to “severe” if additional pollutants are introduced. Skymet Weather Services meteorologist Mahesh Palawat warned that northwesterly winds might bring smoke from stubble burning into Delhi, adding to pollution levels. “If firecrackers are also used, pollutants could become further trapped, worsening air quality,” Palawat stated.
The Diwali smog is fueled by stubble burning in nearby Haryana and Punjab, an annual issue that contributes to the capital’s pollution woes during post-harvest months.
Strict Anti-Pollution Measures in Delhi
Delhi authorities have implemented several steps to counter pollution during Diwali. Environment Minister Gopal Rai announced that 377 teams have been tasked with enforcing the firecracker ban across the city, and Delhi Police officers, led by local Deputy Commissioners, are coordinating efforts in their districts.
The city’s hazardous air quality prompted officials to activate stage two of the Graded Response Action Plan (GRAP) last week. Under GRAP, restrictions on coal and firewood use, diesel generator sets, and construction dust are enforced. Regular mechanical sweeping and water sprinkling on roads are in place, while vehicle parking fees are being raised to discourage private transport. Additional public transport services, including buses and metros, have been deployed to ease commuter reliance on personal vehicles.
Residents have been advised to use public transportation, maintain their vehicle air filters, and avoid dust-generating activities.
Last year, Diwali air quality was the best in eight years, with an AQI of 218. However, today’s numbers reflect the persistent battle against pollution in the face of regional agricultural burning and limited improvements in air quality, despite concerted efforts.
