A potentially unprecedented El Niño phenomenon is rapidly intensifying in the tropical Pacific Ocean. NOAA climate models indicate a 69% probability that the event will surpass the intensity of every major El Niño recorded since 1950 during the October–December 2026 window.
The Ministry of Earth Sciences echoed these projections in Parliament, confirming that Pacific ocean-atmosphere coupling points toward a high-intensity climate event heading into the final quarter of the year. The current southwest monsoon season (June–September) has already felt the pressure of warming Pacific waters. Climate scientists emphasise that while El Niño suppresses southwest monsoon rains, it often acts as a catalyst for enhanced northeast monsoon rainfall (October–December) across Tamil Nadu, Andhra Pradesh, and southern peninsular regions. “While El Niño generally reduces southwest monsoon rainfall, it has typically favoured northeast monsoon rainfall over southern India.

India Meteorological Department (IMD) tracking shows national cumulative precipitation trailing between June 1 and August 14.
“During the October–December 2026 season, there is a 69% chance of a historic event that would exceed the strength of previous El Niño events dating back to 1950,” said the National Oceanic and Atmospheric Administration (NOAA). Early indicators show potential positive impacts for the upcoming late-year season,” said Dr.
