NEW DELHI – North India finds itself in the unforgiving grip of a severe cold wave compounded by dense to very dense fog, creating a profound impact on daily life, health, and critical transportation networks. The prolonged spell of biting cold and drastically reduced visibility has transformed the region, prompting the India Meteorological Department (IMD) to issue orange alerts across multiple states and urging extreme caution among residents. As of early January 2026, large swathes of the northern plains and Himalayan regions are experiencing sub-zero temperatures and conditions that have brought normal routines to a grinding halt.
The cold wave has intensified across a vast geographical expanse, stretching from the high-altitude regions of Ladakh and the Kashmir Valley to the populous plains of Punjab, Haryana, Delhi-NCR, Uttar Pradesh, and Rajasthan. Hilly states like Uttarakhand and Himachal Pradesh are also witnessing significant dips in mercury, alongside parts of Bihar, Madhya Pradesh, Jharkhand, Chhattisgarh, and the northeastern states. In Kashmir, the “Chillai Kalan,” the harshest 40-day winter period that began on December 21, has seen temperatures plummet dramatically. Leh recorded a frigid -9.6°C, while Gulmarg, a popular ski resort, shivered at -8.8°C, marking the season’s lowest. Srinagar registered -3.6°C, further highlighting the severity. Across the northern plains, minimum temperatures have consistently hovered between 1°C and 6°C, with Rajasthan’s Fatehpur recording a low of 1.6°C and Sikar at 2.5°C. Delhi-NCR has experienced minimums ranging from 7°C to 9°C, with daytime temperatures struggling to surpass 17°C to 19°C.
The immediate and most visible consequence of this extreme weather has been the widespread disruption to transportation. Dense to very dense fog has reduced visibility to below 50 meters in many areas, and in some isolated pockets, such as Gorakhpur, Gwalior, and Jabalpur, visibility has dropped to a perilous zero. This has wreaked havoc on air, rail, and road travel. Numerous flights at major airports, including Delhi’s Indira Gandhi International Airport, have faced significant delays, diversions, or outright cancellations. Airlines, along with the Airports Authority of India (AAI), have issued advisories, urging passengers to verify flight statuses and allocate extra travel time. The railway network has also been severely impacted, with dozens of long-distance trains running hours behind schedule, as loco pilots are forced to reduce speeds drastically for safety in the treacherous low-visibility conditions. Road traffic across national highways has slowed to a crawl, increasing commute times and accident risks.
Beyond the immediate travel chaos, the cold wave poses serious health risks, particularly for vulnerable populations. The IMD has cautioned that dense fog, often trapping particulate matter and pollutants, can exacerbate respiratory issues, leading to increased instances of wheezing, coughing, and shortness of breath. The biting cold, combined with exposure, has tragically led to reports of deaths, especially among the homeless. Delhi and Mohali have seen cases where individuals found sleeping in the open are suspected to have succumbed to the extreme cold, underscoring the urgent need for enhanced shelter and relief efforts. Local administrations, such as those in Bundelkhand (affecting 19 districts in Madhya Pradesh and Uttar Pradesh), have responded by declaring school holidays and organizing community bonfires to provide some respite from the harsh conditions.
Meteorological experts attribute the ongoing severe spell to a confluence of factors, including cold winds sweeping in from the northern mountains and the lingering effects of Western Disturbances, which, while bringing some snowfall to higher reaches, also contribute to the overall cold air mass. The La Niña phenomenon is also generally associated with colder-than-normal conditions in northern India. Forecasts from the IMD indicate that these severe cold wave and dense fog conditions are likely to persist for several more days, with some areas expected to experience them until January 11-12. A gradual fall of 2-3 degrees Celsius in minimum temperatures is predicted over northwest India in the coming days before stabilizing.
The agricultural sector also faces a mixed outlook. While freezing temperatures pose a threat to standing rabi crops like wheat and pulses, potentially causing frost damage, a colder January is generally considered beneficial for winter-sown crops during their growth and maturity stages, potentially leading to bumper yields if conditions remain favorable. Farmers have been advised to take precautionary measures, such as lighting small bonfires along field boundaries at night to create a protective layer of smoke and warmth. As North India braces for continued severe weather, authorities are emphasizing vigilance and adherence to safety advisories to mitigate the impact on human life and essential services.
