New Delhi: The India Meteorological Department (IMD) has issued an important warning regarding this year's winter weather. According to the department, the winter of 2025 may be colder and longer than normal.

This is primarily due to a climate condition called La Nina, which has a major impact on the global weather system.

What is La Nina?

La Nina is a cold phase of the El Nino-Southern Oscillation (ENSO). In this phase, sea surface temperatures in the central and eastern Pacific Ocean drop below normal. This change affects global atmospheric circulation, altering rainfall, winter, and storm patterns.

ENSO has three phases:

  • El Nino (warm)
  • La Nina (cold)
  • Neutral (normal)

These cycles vary every two to seven years. This year, there are signs of La Nina, which is likely to lead to more severe and earlier winters in India.

North India Feels Winter Even Before Diwali

Areas like Delhi-NCR, Noida, Gurgaon, and Ghaziabad are experiencing light fog and cold mornings. The retreating monsoon is expected to bring light rain in the coming weeks, further intensifying the cold.

Snowfall has already begun in hilly states like Himachal Pradesh and Jammu and Kashmir, causing temperatures to drop sharply.

La Nina's Impact in South India

Not just North India, South India will also be untouched by this change. Above-normal rainfall is expected in Tamil Nadu, Kerala, and Andhra Pradesh during the northeast monsoon, which lasts from October to December. The IMD estimates that these regions could receive up to 112% of the average.

Air Pollution: Another Challenge

As temperatures drop in Delhi and its surrounding areas, air pollution is also increasing. Currently, air quality is in the "moderate" category, but as the cold increases, it could move into the "poor" category, impacting health.

Advice for Citizens and Farmers

The IMD has advised citizens to prepare for winter in advance, especially the elderly and children. This weather change is also important for farmers, as extreme cold can affect crops.
