What to know

  • Delhi's AQI reached 310 on November 2—the worst since February—despite new pollution control measures taking effect November 1.
  • Neighboring Noida also entered 'very poor' category at 311; smog blanketed central Delhi with some stations recording readings as high as 417.
  • The Union's early warning system forecasts 'very poor' air to persist through November 10, driven by winter meteorology, stubble burning, and Diwali pollution.
  • Stricter vehicle-entry restrictions barring non-BS-VI vehicles from entering Delhi have so far failed to reverse the sharp pollution spike.

“The air quality of Delhi is likely to be in the 'poor' to 'very poor' category for about five to six days, as per the Central government's 'Air Quality Early Warning System for Delhi'.”

  1. background

    Union government forecasts 'very poor' air to persist through November 10 — The Union's Air Quality Early Warning System predicted pollution would remain in the 'poor' category through Tuesday, November 4, then worsen to 'very poor' on Wednesday, November 5, and stay 'very poor to poor' until November 10. Experts attribute the worsening to winter meteorology, stubble burning, Diwali firecrackers, vehicle emissions, and coal plant pollution.
