Delhi’s AQI stood at 339 on January 15, remaining in the very poor category yesterday. As compared to Saturday, the air quality of Delhi has seen a slight improvement.

Meanwhile, the cold day conditions in Delhi prevailed on Sunday morning, with little to no sunlight due to the thick fog. The national capital recorded the season's lowest maximum temperature at 14.8 degrees Celsius this morning.

An IMD official said, “Today also there was a layer of moderate fog/low cloud over Delhi-NCR, Punjab, Haryana, Uttar Pradesh, and north Rajasthan. It prevented the sunlight from reaching the surface. Light north westerlies are also blowing over the region. These conditions led to a cold day.”

The weather department recorded the minimum temperature at the Safdarjung Observatory, which is considered the official marker for the city, at 6.1 degrees Celsius in the morning, which is just a notch below the normal temperature.
