Delhi Air Quality Index Overview
Delhi's air quality index remained in the "very poor" category on Wednesday morning, October 22, 2025, with the overall AQI recorded at 345 as of 6 AM. The capital woke up to a thick layer of smog and toxic air for the second consecutive day after Diwali, as pollution levels continued to soar despite GRAP 2 restrictions being in place. The Central Pollution Control Board data shows that 36 out of 38 monitoring stations across Delhi recorded air quality in the red zone, indicating "very poor" to "severe" conditions.
This year's post-Diwali pollution marks a concerning trend, with the AQI of 345 on Diwali night being worse than last year's 328 and significantly higher than the 218 recorded in 2023. PM2.5 levels reached alarming concentrations of 262 µg/m³, which is over 59 times the World Health Organization's annual guideline.

Delhi Diwali Pollution and Weather
Despite Supreme Court guidelines limiting green crackers to 8-10 PM, widespread violations pushed PM2.5 and PM10 concentrations to 15-18 times safe limits, with peaks above 1,400 µg/m³ at Anand Vihar, Dwarka, and Jahangirpuri. Delhi temperature today stands at 25°C with mist, 89% humidity, and calm wind speeds of 4-5 km/h, preventing pollutant dispersion. Residents are advised to wear N95 masks, use air purifiers, and limit outdoor activities until air quality improves.
