Delhi shivers at 7 degree Celsius as dense fog envelops North India
Delhi woke up to a shivering Monday (December 27) morning as a dense blanket of fog enveloped the national capital and its neighbourhood, reducing visibility and making commute difficult for people.
Dense to very dense fog conditions were also reported in neighbouring Haryana, Punjab and Uttarakhand.
In Delhi, the temperature recorded was 7 degrees Celsius on Monday morning.
The India Meteorological Department (IMD) on Monday had predicted dense to very dense fog conditions to persist over the next few days.
“Cold day/severe cold day conditions very likely in some parts over Punjab, Haryana, Chandigarh, Delhi and West Rajasthan and cold day conditions in isolated pockets over Uttarakhand on 26th and 27th December 2022,” the IMD said in a bulletin on Monday.

According to the IMD, very dense fog is when visibility is between 0 and 50 metres, 51 and 200 metres is dense, 201 and 500 moderate, and 501 and 1,000 shallow. In the plains, the IMD declares a cold wave if the minimum temperature dips to 4 degrees Celsius. A cold wave is also declared when the minimum temperature is 10 degrees Celsius or below and is 4.5 notches below normal. A severe cold wave is when the minimum temperature dips to two degrees Celsius or the departure from normal is more than 6.4 degrees Celsius.
A severe cold wave gripped the region with the maximum temperature plummeting 10 degrees below normal in Delhi. Meteorologists attributed the sharp drop in day temperatures to frigid north-westerly winds barrelling through the plains and reduced sunshine due to foggy weather.
In Delhi, dense fog lowered visibility to 50 metres in some areas, affecting road and rail traffic. Ten trains were reported running late by 1.45 to 3.30 hours, a Railway spokesperson said.
The mercury dropped to 3 degrees Celsius in the Ridge area, 4.9 degrees below normal, making it the coldest place in the national capital. The Ridge and the Ayanagar weather stations recorded a minimum temperature of 4 degrees Celsius and 4.1 degrees Celsius, respectively. The Safdarjung observatory, Delhi’s primary weather station, logged a minimum temperature of 5 degrees Celsius – three notches below normal on Monday. The Palam observatory recorded a minimum temperature of 6.5 degrees Celsius and a maximum of 12.5 degrees Celsius, a departure of nine degrees Celsius from normal. Jafarpur in southwest Delhi logged a minimum temperature of 4.2 degrees Celsius and a maximum of 11 degrees Celsius, 10 notches below normal. Mungeshpur in northwest Delhi recorded a minimum temperature of 5.3 degrees Celsius and a maximum of 11.4 degrees Celsius against the season’s normal maximum temperature of 21.4 degrees Celsius.
The automatic weather stations at Ayanagar, Lodhi Road, Ridge, Najafgarh, Pitampura, and Mayur Vihar recorded a maximum temperature of six to eight notches below normal. Mahesh Palawat, vice president (meteorology and climate change), Skymet Weather, said a western disturbance led to a fresh spell of snowfall in the mountains on December 25-26 and cold north-westerly winds are now sweeping through the plains after its retreat.

“An increase in the humidity levels due to the WD resulted in dense to very dense fog which reduced the sunshine, pulling down the day temperature further,” he told PTI. Palawat said the wind chill factor – a measure of the rate of heat loss from skin that is exposed to the air – is also high. The higher the wind speed during cold weather, the colder it feels on the skin if a person is outside.
Delhi clocked a top wind speed of 15 km per hour on Monday. Biting cold conditions and dense fog were reported in several parts of Punjab and Haryana, with Narnaul being the coldest in the region at 2.4 degrees Celsius. In Haryana, Hisar recorded a piercing cold as the minimum temperature plunged to 2.5 degrees Celsius. Ambala recorded a low of 7.7 degrees Celsius, Karnal 6.8 degrees Celsius, Rohtak 6.6 degrees Celsius, Bhiwani 5.5 degrees Celsius, and Sirsa 5.2 degrees Celsius. Chandigarh, the joint capital of Punjab and Haryana, recorded a minimum temperature of 7.4 degrees Celsius. In Punjab, Amritsar recorded a low of 6.5 degrees Celsius, Ludhiana 6 degrees Celsius, Pathankot 8.8 degrees Celsius, Bathinda 3.6 degrees Celsius, Faridkot 6 degrees Celsius, and Gurdaspur 4.5 degrees Celsius.
