Delhi Experiences Cold Wave and 'Poor' Air Quality Despite Cleaner December Start

The capital recorded its cleanest early December since 2015 but now faces plummeting temperatures and worsening air pollution.

Delhi's average AQI between December 1 and 15 was 238, the lowest for this period since AQI monitoring began in 2015.
The city recorded six 'moderate' air quality days in December, the highest since 2018, but air quality has recently worsened to 'poor' levels, with AQI at 246 on Sunday morning.
A severe cold wave has gripped Delhi, with temperatures dropping to 4.9°C on Sunday, marking the third time this winter season the mercury has fallen below 5°C.
Meteorologists attribute improved early December air quality to strong winds and reduced fog, but warn pollution levels could rise further as wind speeds slow in coming days.
Shelter homes in Delhi have seen increased occupancy as residents seek refuge from the harsh cold, with facilities providing food, blankets, and medical assistance.
