Today · 26 July 2026

Delhi's average PM2.5 today is 32.8 µg/m³ and PM10 is 83.8 µg/m³. 39 of 44 stations breached the WHO limit for PM2.5; 39 of 42 breached it for PM10. Gas monitoring was down on this date, so this edition reports the two particulate pollutants directly, in micrograms per cubic metre, and publishes no composite index figure.

Analysis window: 10 AM 25th July to 10 AM 26th July
Baseline: YoY baseline: avg of 19th Jul - 2nd Aug 2025 (same +/-7 days), matched stations
A caution we publish daily: Gas monitoring was down on this date: NO2 reported from 10 stations, SO2 reported from 9 stations, CO reported from 11 stations, against about 44 for PM. That is too thin to carry a reliable finding, so this edition reports PM2.5 and PM10 only, directly in micrograms per cubic metre. No composite AQI figure is published today.

Taking the weather out

How we separate the pollution the city produced from the weather it happened to get, and why that is the only honest comparison.

With special thanks to the Centre for Research on Energy and Clean Air (CREA). Its hourly compilation of the official station data is what this analysis is built on, and its own work has done a great deal to create public awareness of the air.
