Delhi's air turns toxic: AQI hits 461, worst winter day yet

India Dec 14, 2025

Delhi's air quality plunged to a 'severe' level on Sunday, with the city's average AQI spiking to 461—the highest this winter and nearly the worst ever for December.
The IMD expects moderate fog and chilly weather around 23°C/8°C, but only light winds, so pollution is likely to stick around.

Why does it matter?

With weak winds and high humidity trapping pollutants, areas like Wazirpur and Rohini saw AQI readings max out at 500.
This kind of air can harm everyone—especially because PM2.5 particles get deep into your lungs.
Health expert Shila Yadav suggests skipping outdoor workouts, wearing masks outside, and eating seasonal fruits to help your body cope.
Authorities have also rolled out the strictest anti-pollution measures (Stage IV GRAP) in response.
