10.1°C: Mercury falls to season's lowest; AQI still 'very poor'

Cold, northwesterly winds led to a sharp dip in Delhi's mercury, with the Capital's minimum dropping to 10.1 degrees Celsius (°C)—the lowest of the winter season so far, India Meteorological Department (IMD) data showed.

The winds, blowing at speeds of 10-12kmph, also kept Delhi's pollution levels in "very poor" zone—the Central Pollution Control Board (CPCB) national bulletin stated that the Capital's average air quality index (AQI) reading at 4pm was 325, a slight deterioration from the previous day's reading of 303. But as wind speeds dropped towards evening, the city's AQI began rising, increasing to 332 at 7pm, and staying at 331 by 10pm.
