Super El Niño 2026: Is India Heading Into Its Worst Monsoon in Decades?

India's monsoon feeds half its farmland, drives its kharif harvest, and ultimately underpins the food security of over a billion people. In 2026, all of that is under pressure from a single, rapidly intensifying climate event in the Pacific Ocean.

India is heading into the southwest monsoon season under the shadow of a rapidly strengthening El Niño, with meteorologists warning that the climate phenomenon could significantly disrupt rainfall patterns, intensify heat stress and place additional pressure on the country's agriculture-dependent economy. The India Meteorological Department (IMD) has already issued a clear signal: this year's monsoon could be the most difficult in recent memory.

What Is Super El Niño - and Why Does It Matter for India?

El Niño refers to the abnormal warming of sea surface temperatures in the equatorial Pacific Ocean. In a Super El Niño, that warming is stronger and more sustained - enough to reshape weather patterns across Asia, Africa, and the Americas simultaneously.

For India, the link is direct. A warm Pacific suppresses the moisture-laden winds that drive the southwest monsoon. The result: reduced rainfall, delayed onset, longer dry spells, and erratic distribution across states that depend on June-to-September rains for nearly 80% of their annual precipitation.

"The numerical model forecasts that the evolving El Niño event could match the Super El Niño seen four decades ago," said GP Sharma, President of Meteorology and Climate Change at Skymet Weather and former Air Vice Marshal of the Indian Air Force.

The last comparable event, the 2015-16 Super El Niño, is the reference point most scientists are reaching for. During the 2015-16 Super El Niño, India's monsoon rainfall fell to 86 per cent of the long-period average, triggering drought-like conditions across several states.

The IMD has forecast below-normal rainfall for the 2026 monsoon season, projecting seasonal precipitation at 90 per cent of the Long Period Average (LPA) of 870 mm, with an error margin of plus or minus four per cent.

The probability of a deficient season, rainfall below 90 per cent of LPA, is 35 per cent, more than double the long-term climatological probability of 16 per cent. Chances of a below-normal season stand at 31 per cent. The chances of above-normal or excess rainfall are just 6 per cent and 1 per cent, respectively.

There are potential counterweights. IMD Director General Mrutyunjaya Mohapatra noted that the development of positive Indian Ocean Dipole (IOD) conditions and below-normal snow cover over the northern hemisphere could counter some impacts of El Niño conditions. However, current modelling shows a neutral IOD for the rest of the year, leaving the subcontinent without a natural buffer, the same buffer that helped India survive the 1997-98 El Niño cycle.

The Stakes for Farmers, Food and the Economy

More than 50 per cent of India's agricultural land is still rain-fed, making the sector highly vulnerable to a Super El Niño-induced weak monsoon. Reduced rainfall and prolonged dry spells can adversely affect kharif crop yields. Lower agricultural output would inevitably exert upward pressure on food prices and contribute to inflation.

The adverse consequences could affect about 60 per cent of farmers in the country reliant on monsoon rainfall for the kharif season. Rice, pulses, sugarcane, and oilseeds are among the most exposed crops.

Predictions suggest this could be one of the worst monsoons in the past 150 years.

Beyond farms, scientists warn of wider cascading effects. Experts cautioned that delayed monsoon progress could trigger humid heatwaves in northwest India if hot winds combine with moisture from the Arabian Sea during July and August. A weak monsoon could also trigger wider economic consequences, including food inflation, rising electricity demand, and slower rural consumption.
