La Niña’s Cold Grip: What Delhi’s Early Shivers Mean for Millions This Winter

Understanding La Niña and Its Significance

La Niña is the cool phase of the El Niño-Southern Oscillation (ENSO), characterized by lower-than-average sea surface temperatures in the central and eastern Pacific Ocean. This shift alters atmospheric circulation, influencing weather patterns worldwide. According to the India Meteorological Department (IMD) and the US NOAA, La Niña conditions have emerged and may persist through early 2026, signaling potentially colder winters for India.

Impact on Indian Climate

Colder Winters in North India: Expect below-average minimum temperatures in Delhi-NCR, Punjab, Haryana, Uttar Pradesh, and Bihar, with early onset of chilly weather.

Increased Himalayan Snowfall: Jammu & Kashmir, Himachal Pradesh, and Uttarakhand could see heavier snowfall, beneficial for water reservoirs but disruptive for transport.

Frequent Fog and Frost: These conditions may increase over northern plains, affecting crops and daily activities.

Extended Cold Waves: Prolonged cold spells could strain energy resources and public health.

Notable Updates

Duration & Intensity: The current La Niña episode is classified as mild but timely, with over 60% probability of continuation till February 2026.

Early Cold Episodes: Reports of early snowfall and temperature dips hint at this year’s significant cold season.

Historical Trends: Past La Niña events have correlated with harsh northern winters in India, often accompanied by agricultural challenges.

Regional Variation: Effects strongest in northern and Himalayan regions, with moderate impact elsewhere.

Preparedness Measures: Authorities recommend early warnings, safeguarding vulnerable populations, and crop protection strategies.

Major Takeaways

La Niña’s return points towards a winter requiring concerted preparation across sectors in India. While colder temperatures and snowfall pose challenges, the phenomenon also typically leads to stronger monsoon rains later, potentially aiding agriculture recovery.
