Delhi recorded its first ‘poor’ air quality day of the season on Wednesday, 21 October, with an AQI of 227 at 7 am, according to the Central Pollution Control Board. The reading had crossed the ‘poor’ threshold of 200 at 2 am and did not dip below it since. The deterioration followed Dussehra celebrations on Tuesday, 20 October, which involved effigy burning and fireworks.

Two monitoring stations, Jahangirpuri and Pusa, entered the ‘very poor’ category at 308 and 314. The Air Quality Early Warning System forecast that the AQI would stay in the ‘poor’ category until at least Friday, 23 October, and could reach 342 on 22 October, which is ‘very poor’. The last time Delhi recorded poor air quality was on 12 and 13 July. The Delhi government’s winter action plan, including a ‘No PUC, No Fuel’ policy and restrictions on non-BS-VI vehicles, is scheduled to take effect from 1 November.
All six sources report Delhi's first ‘poor’ AQI of the season on 21 October, attributing it to Dussehra firecrackers and seasonal weather, with uniform straight reporting that includes the same CPCB figures, the AQEWS forecast of ‘poor’ air until 23 October and a projected AQI of 342 on 22 October. Hindustan Times adds a satellite farm-fire count of 182 in Punjab and Haryana in the three days to 20 October, 397 since 1 October, but notes the count is an underestimate, no other source picks up this detail. Times Now lists specific Delhi government measures such as the ‘No PUC, No Fuel’ policy effective from 1 November, a fact absent from most others. Open Magazine alone compares 2025’s 79 good-air days and 165 bad-air days, providing a seasonal benchmark.
