Denizens woke up on Monday morning to find a thick blanket of fog engulfing the city, the first of the season.
Life was thrown out of gear as the dense fog disrupted flights and train schedules, besides public transport.
On Monday, the maximum temperature was registered at 21.0 Degrees Celsius, while the minimum was 6.0 degrees Celsius.
The arrival timings of several flights, including international and domestic ones, were disrupted.
Officials at the Sri Guru Ram Das International Airport said the Turkmenistan Airlines flight, scheduled for 9AM, was delayed by 2 hours and 47 minutes, thereby arriving at 11:47 AM.
Two Air India flights en route from New Delhi were delayed by more than two hours.
The airport officials said the Spicejet 442-from Mumbai to Amritsar via New Delhi was also delayed due to fog at Delhi. Three other SpiceJet flights from Delhi to Amritsar were also affected.
Due to foggy weather conditions, the schedules of trains were also disrupted.
Shatabdi was delayed by almost one-and-a-half hour. Even as the prolonged spell of fog can be harmful for the wheat crop, agriculturists in the city don't see any threat to the same at the moment.
"The cold weather is good for the crop but not the fog. It can damage the wheat crop, but farmers can prevent the same by ensuring that they don't irrigate the crops unnecessarily. As of now, there is no threat to the crop. It is yet to be seen whether the spell of fog will be prolonged or short-lived," said Dilbagh Singh Dhanju, district agriculture officer.
Meanwhile, with winter tightening its grip around the city, residents could be seen dressed in woollens, coats, jackets, scarves and socks that had hitherto been tucked away in wardrobes.
A majority of the residents, particularly schoolchildren, office-goers, labourers and milk vendors, coming from far-flung villages could be seen braving the chill on foot or two-wheelers to reach their destinations.
In view of the intensifying chill, many educational institutions around the city have altered their timings by half-an-hour to one hour.
The cold wave has claimed more than a couple of lives in the past few days.
