Strong El-Niño, Uneven Monsoon Not Just A 2026 Story! Phenomenon Could Last Till 2027, Warns Scientists

Strong El Niño has already cast its shadow on India's monsoon season in 2026, but experts warn that the phenomenon could extend beyond this year. Early climate model signals from the tropical Pacific are drawing attention because they point to a possible strong El Niño episode developing by late 2026, continuing into 2027, and impacting the monsoon for another year.

Monsoon in India has arrived, but the India Meteorological Department (IMD) has predicted below-normal rainfall at 90% of the long-period average. As per the weather forecasting agency, there is a 60% chance of a deficient monsoon.

Strong El Niño Episode Can Develop By Late 2026s

Early climate model signals from the tropical Pacific have hinted towards a stronger El Niño episode by late 2026. As per the India Today report, if a strong El Niño develops by late 2026, it can continue till 2027.

What Does A Strong El Niño Mean For India?

If the projections hold, the event could influence rainfall, food prices, energy demand and disaster preparedness across several regions, including India. The concern about Strong El Niño comes from long-range sea surface temperature forecasts. It also includes the North American Multi-Model Ensemble outlook for November-December-January 2027.

Some model runs indicate unusually warm waters across the central and eastern equatorial Pacific, with temperatures more than 2 degrees Celsius above normal in key zones.

Such readings would place the event in the category of a very strong El Niño, though scientists treat forecasts this far ahead with caution. Long-range climate models can identify broad trends, but the eventual strength, timing and regional impact may change as atmospheric and oceanic conditions evolve.

Risk Of Uneven Monsoon

Scientists in India closely track El-Nino patterns and intensity because it has a direct impact on Monsoon rainfall. India receives more than 60% of its annual rainfall from monsoon rainfall. It supports agriculture, reservoir levels, rural incomes and food supply chains.

Even a moderate disruption can affect inflation expectations, crop output and government planning for water and power demand.

El Nino-Monsoon Relation

India has seen years when El Niño did not produce a severe drought, because other climate systems also shape the monsoon. The Indian Ocean Dipole, Eurasian snow cover, local sea temperatures and intra-seasonal rainfall patterns can either worsen or offset El Niño's influence.

Even so, a very strong El Niño signal would be important for policymakers and markets. Rainfall shortfalls can affect sowing decisions for crops such as rice, pulses, oilseeds and sugarcane. They can also push up irrigation demand, diesel use, electricity consumption and pressure on groundwater resources.

Financial markets usually track these risks through food inflation, rural consumption, fertiliser demand, fast-moving consumer goods sales and farm-linked sectors. For a finance-focused audience, the weather event is not only a scientific development. It is also a macroeconomic variable that can influence prices and policy responses.

What is El Nino?

It is a naturally occurring climate phenomenon that occurs in the tropical Pacific Ocean. It consists of the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean. It recurs every two to seven years and last for 9 to 12 months.

El Niño develops when surface waters in the central and eastern equatorial Pacific become warmer than usual. This warming alters wind patterns and shifts rainfall zones across the tropics. The changes can then influence weather far beyond the Pacific, including Asia, Africa, Australia and the Americas
