The real-time Central Pollution Control Board monitoring reports that AQI index dropped 12 points compared to yesterday, November 8th.
Despite the slight drop toxic particulate matter remains high. 47 out of 49 active stations as of today is identifying fine particles as the primary pollutant.
Graded Response Action Plan Stage Two restrictions remain in full force across the Indian capital city. Read more about the latest AQI today and yesterday along with other recorded highs hereon.

What was Delhi AQI Yesterday, on Diwali 2026?
Delhi recorded an unimaginable environmental spike yesterday on Diwali night, November 8, 2026.
The real-time sensor networks logged Delhi's midnight Air Quality Index to a peak of 1331 at 1:31 AM. The reading set one of the highest recorded real time pollution spikes worldwide.
Fine particulate concentrations in hotspots like Anand Vihar exceeded World Health Organisation limits by over 50 times. And briefly it made Delhi the most polluted megacity in the world before settling at a 24-hour average of 376.
5 Highest Recorded Diwali AQI Levels in Delhi History
To put current AQI readings in context Delhi has witnessed far more intense post celebration air emergencies since official index tracking began. Historical Central Pollution Control Board bulletins record the five highest citywide twenty four hour average AQI readings on the day after Diwali:
#1. 2021 (November 5)
462 (Severe): Dense farm smoke merged with firecracker emissions which marked the worst post festival air on record.
#2. 2016 (October 31)
445 (Severe): The historic smog crisis that triggered Delhi's first comprehensive emergency interventions.
#3. 2020 (November 15)
435 (Severe): Cold weather and calm boundary layer winds locked thick smog across the entire plains.
#4. 2017 (October 20)
403 (Severe): Widespread crop residue burning upstream pushed the entire national capital past the severe baseline.
#5. 2018 (November 8)
390 (Very Poor to Severe border): Persistent stagnation kept particulate loads trapped at ground level for days.
Why Fine Particles Keep Smog Trapped Over the Plains
Even with a 12-point overall decline in AQI PM2.5 particles remain suspended at critical thresholds. These microscopic specks measure less than 2 micrometres in diameter. This allows them to penetrate deep into the lungs and enter the bloodstream.
Winter temperature inversions create an invisible lid over North India.
As cooler air stays pinned beneath warmer layers, vehicular exhaust, industrial fumes, and post-harvest biomass smoke cannot escape upward. And without sustained surface wind speeds above ten kilometers per hour the capital remains an enclosed basin for accumulated smoke.
What is Public Advisory and Active Enforcement Un
Under Stage Two curbs, municipal teams are operating mechanical road sweepers, applying anti-smog water misting, and inspecting diesel generator operations.
Health experts urge morning walkers, runners, and school children to limit prolonged outdoor exposure during early hours. High-efficiency filtration masks provide personal defense, while residents should keep indoor air purifiers running until wind patterns shift later this week.
