Winter Weather Extremes Highlight Climate Variability in India

Early January 2026 witnessed severe cold-wave conditions accompanied by dense and persistent fog across large parts of northern India, including the Indo-Gangetic plains. These weather extremes disrupted road, rail, and air transport, led to the closure of schools in several states, and placed additional strain on public health services. The episode once again underscored the growing impact of climate variability on seasonal weather patterns in India.

Cold waves and fog events are classified as climate-related extreme weather phenomena by the India Meteorological Department (IMD). Scientific assessments indicate that climate change is increasing the frequency, intensity, and unpredictability of such extremes. Western disturbances, temperature inversions, calm wind conditions, and high moisture levels often combine to produce prolonged cold spells and dense fog, particularly during winter months in northern India.

The socio-economic consequences of these events are significant. Vulnerable groups such as the elderly, children, homeless populations, and outdoor workers face heightened health risks, including hypothermia and respiratory illnesses. Transport disruptions affect supply chains, economic productivity, and emergency services, while school closures disproportionately impact children from marginalised backgrounds who rely on institutional support systems.

The events highlighted critical gaps in disaster preparedness and governance. While heat waves and floods have received increasing policy attention, cold waves and fog events remain relatively under-addressed in disaster management frameworks. Early-warning dissemination, inter-agency coordination, and local-level response mechanisms are often reactive rather than anticipatory. Urban areas, in particular, lack winter-specific climate resilience planning.

Addressing these gaps requires mainstreaming winter weather extremes into disaster risk reduction strategies. Strengthening IMD forecasting and communication, expanding temporary shelters and warming centres, issuing timely public health advisories, and integrating cold-wave action plans into State Disaster Management Plans are essential steps. Urban planning must also incorporate climate-sensitive design to reduce exposure risks.

In conclusion, winter weather extremes in early 2026 highlight the need to recognise climate variability as a year-round governance challenge. Proactive preparedness and adaptive planning are crucial to protecting lives, livelihoods, and critical infrastructure in a changing climate.
