Delhi Shivers at 4.2°C: Season’s Lowest Temperature Recorded, 20+ Flights Affected by Cold Wave

Delhi shivers at 4.2°C, the season’s lowest temperature so far, as cold wave conditions disrupt flight operations at IGI Airport

Delhi experienced its coldest morning of the season as the minimum temperature plunged to 4.2 degrees Celsius, sending a sharp chill across the national capital. The sudden dip in temperature, accompanied by cold wave conditions, dense fog in pockets, and reduced visibility, disrupted normal life and significantly affected flight operations at Indira Gandhi International (IGI) Airport.

The sharp fall in mercury marks one of the coldest spells this winter and has prompted authorities to issue advisories as residents brace for more chilly days ahead.

According to meteorological data, the temperature drop to 4.2°C is the lowest recorded in Delhi this season so far. Several parts of the city, especially low-lying and open areas, reported biting cold conditions early in the morning hours. The chill was felt more intensely due to cold northerly winds, which lowered the “feels-like” temperature.

Weather experts classify the conditions as a cold wave, a phenomenon that occurs when temperatures fall significantly below normal levels for consecutive days. In Delhi, cold wave conditions are often accompanied by fog, calm winds at night, and clear skies, allowing heat to escape rapidly.

The cold wave and poor visibility led to disruptions in flight operations at Delhi’s IGI Airport, one of the busiest aviation hubs in the country. Several flights were delayed, while a few were reportedly diverted due to low visibility during early morning hours.

Airport authorities confirmed that fog and cold weather affected landing and take-off schedules, particularly for flights not equipped with advanced navigation systems. Airlines issued travel advisories, urging passengers to check flight status before heading to the airport.

While operations gradually improved as visibility conditions got better later in the morning, the early disruption caused inconvenience to hundreds of passengers, many of whom faced long waiting hours.

In addition to the temperature drop, dense fog was reported in several parts of Delhi and adjoining regions. Visibility levels dropped sharply during the pre-dawn and early morning hours, affecting road, rail, and air traffic.

Major arterial roads witnessed slower traffic movement, while drivers were advised to use fog lights and maintain safe distances. Train services also experienced minor delays as precautionary measures were implemented to ensure passenger safety.

Meteorologists noted that fog conditions are likely to persist over the next few days, especially during night and early morning hours, as moisture levels remain high and wind speeds stay low.

The cold wave has had a noticeable impact on daily life in the capital. Early morning walkers, street vendors, construction workers, and sanitation staff were among the most affected, struggling to cope with the biting cold.

Homeless shelters across the city reported an increase in occupancy as people sought refuge from the harsh weather. Authorities activated night shelters and distributed blankets in vulnerable areas to prevent cold-related illnesses.

Doctors have advised people, especially children, the elderly, and those with respiratory or cardiac conditions, to take precautions. Prolonged exposure to cold can worsen ailments such as asthma, arthritis, and blood pressure issues.

Although schools and offices remained open, attendance in early morning shifts was reportedly affected. Parents expressed concerns about children stepping out in extreme cold, while several institutions advised students to dress warmly.

Outdoor workers faced significant challenges, with many delaying start times until the sun rose and temperatures became more bearable. Tea stalls and street food vendors saw increased demand for hot beverages, as residents sought warmth during commutes.

Meteorologists explain that the sharp dip in temperature is due to cold northwesterly winds blowing from snow-covered regions, combined with clear skies at night. These conditions allow rapid heat loss, causing temperatures to fall sharply.

Additionally, the absence of cloud cover and calm wind conditions during nighttime create ideal circumstances for cold wave development. Experts say that such temperature drops are not uncommon during peak winter but the intensity can vary year to year.

Weather officials have predicted that cold wave conditions may continue for the next few days, with minimum temperatures remaining well below normal levels. While daytime temperatures are expected to rise slightly due to sunlight, nights and early mornings will continue to be cold.

Fog is likely to persist, particularly in low-lying areas and along river belts. Residents have been advised to stay updated with weather alerts, especially those planning early morning travel.

With flight and transport disruptions possible, travellers are advised to:

Check flight and train status in advance
Allow extra travel time for airport and railway station commutes
Follow airline advisories related to fog and low visibility
Keep necessary documents and warm clothing handy

Airlines may continue to adjust schedules depending on weather conditions, especially during early morning hours.

Climate experts note that extreme temperature variations are becoming more frequent, with winters experiencing sudden cold spells and summers witnessing prolonged heatwaves. While cold waves are a natural winter phenomenon, their increasing unpredictability has raised concerns among scientists.

Urban factors such as pollution, construction, and changing land use patterns also influence how cold is felt in cities like Delhi. Smog combined with fog can further trap cold air near the surface, intensifying the chill.

Delhi authorities have activated cold wave response mechanisms, including:

Increasing capacity at night shelters
Distributing blankets to homeless populations
Coordinating with health departments for emergency response
Issuing public advisories on cold-related safety

Officials have urged residents to report cases of people sleeping in the open so that assistance can be provided promptly.

Many Delhi residents described the morning as the coldest they had experienced this season. Social media platforms were flooded with posts about frozen mornings, fog-covered streets, and delayed travel plans.

Commuters shared images of misty roads and low visibility, while others joked about staying indoors wrapped in layers. Despite the inconvenience, many welcomed the chilly weather as a hallmark of peak winter in the capital.

As Delhi moves deeper into the winter season, more cold mornings are likely. Weather experts say that while temperatures may fluctuate slightly, cold wave conditions could recur depending on wind patterns and cloud cover.

Residents are advised to stay cautious, especially during early morning and late-night hours, and to follow health and travel advisories issued by authorities.
