Delhi-NCR: Dense fog and toxic air throw travel into chaos

India Dec 31, 2025

Delhi and the NCR woke up to thick fog and a heavy dose of pollution on Monday, making travel a real struggle.
Visibility dropped to just 50 meters at key airports, leading to over 550 flight delays, more than 100 cancelations, and 16 diverted flights.
Train schedules took a hit too, with over 50 running late.

Why does this matter?

The air quality in Delhi hit "very poor" levels (AQI 388), with Ghaziabad even worse at "severe."
The IMD has put out a red alert for dense fog, so expect more tough mornings ahead.
December 2025 is shaping up to be the worst for Delhi's air since 2018—five days so far this month have been labeled "severe," with a sixth forecast for December 31.
Bundle up: temperatures are set to drop further as northwesterly winds arrive soon.
