Delhi Air Quality Worsens the Morning After Diwali: AQI Crosses 400 Into the Severe Range at Many Stations, City Average of 370 Rated Very Poor
NEW DELHI — Air quality in India's capital deteriorated sharply on the morning after Diwali, which fell on November 8. Data from the Central Pollution Control Board put Delhi's Air Quality Index at 370 at 9 a.m. on November 9, in the "very poor" category, while many monitoring stations across the city crossed 400 into the "severe" range.
Station readings included 441 at Burari Crossing, 437 at Vivek Vihar, 434 at Delhi Technological University, 433 at both Jahangirpuri and Delhi University's North Campus, 430 at Rohini and 418 at Ghazipur. Reuters reported that residents set off fireworks in violation of court orders; India's Supreme Court had allowed only certified low-polluting "green" firecrackers, during limited hours over the Diwali weekend. On Swiss firm IQAir's live ranking, Delhi was the third-most polluted city in the world on Monday morning, behind Lahore in Pakistan at 563, a hazardous reading.
The Commission for Air Quality Management had invoked Stage III of the Graded Response Action Plan across Delhi-NCR on the Friday before Diwali, bringing stricter vehicle restrictions, a halt to construction and hybrid classes for primary school students. A Hindustan Times comparison of six consistently reporting stations found this year's Diwali pollution was the third worst since 2021, with the peak hourly PM2.5 sub-index averaging 655 in the hour ending at 1 a.m. after the festival.
