Overview
- Authorities revoked all Stage III measures across the NCR after Delhi’s 24-hour average AQI fell to about 235, while Stage I and II actions remain in place.
- Strong surface winds of roughly 15–20 km/h were credited with dispersing pollutants and driving the rapid one-day drop from around 380.
- Forecasts from AQEWS and SAFAR point to a return to very poor air from Sunday, with SAFAR warning levels could approach 390 later today.
- By early Sunday, the citywide AQI was near 298 in the poor category, and several stations such as Anand Vihar and Rohini registered very poor readings above 300.
- Dense fog under an IMD yellow alert led to dozens of flight cancellations and widespread delays at Delhi airport, and cold-wave conditions are expected in pockets through January 7.
