El Niño is the periodic warming of sea-surface temperatures across the central and eastern equatorial Pacific. It is one of three phases of the El Niño Southern Oscillation (ENSO), the large-scale ocean-atmosphere interaction that shapes weather patterns across the globe. The other two phases are the neutral state and La Niña, which represents the opposite cooling of the same Pacific waters. ENSO is among the most powerful natural climate drivers on Earth.
When an El Niño event is exceptionally strong, associated with unusually high Pacific Ocean temperatures that persist well beyond normal thresholds, it earns the informal label "Godzilla El Niño." The World Meteorological Organization has indicated that the current developing event could reach that intensity by the end of 2026, with effects potentially extending into 2027. That warning carries weight. Strong El Niño years have historically coincided with some of the worst agricultural and hydrological disruptions across the tropics.
The measurement is more precise than the dramatic nickname suggests. Scientists focus on the Niño 3.4 region, a defined stretch of the equatorial Pacific between 5°N–5°S and 120°W–170°W, and track how much its sea-surface temperatures deviate from long-term averages. The formal metric is the Relative Oceanic Niño Index, or RONI. When the three-month average RONI exceeds +0.5°C, an El Niño is officially declared; when it falls below −0.5°C, La Niña is declared instead.
A Godzilla-class episode implies anomalies well above that baseline, sustained over time and accompanied by characteristic shifts in atmospheric circulation such as weakened trade winds.
India's vulnerability to El Niño is structural. The southwest monsoon delivers roughly 70% of the country's annual rainfall, and El Niño events are reliably associated with its weakening. The 2026 monsoon season ended at 87% of the Long Period Average. That deficit, taken alone, is not catastrophic, but it cascades through the agricultural calendar in compounding ways.
Lower rainfall reduces kharif crop yields directly and increases dependence on groundwater and reservoir storage, both already under stress in many states. Warmer winters, another signature of strong El Niño years, disrupt the temperature-sensitive growth stages of rabi crops, particularly wheat, which requires a period of cold to develop properly. The combined effect on output pushes food prices upward, with the burden falling disproportionately on low-income households.
Globally, the footprint is uneven. Above-normal rainfall is expected across the Arabian Peninsula, central and east Asia, and coastal Southeast Asia. Southern Africa, southern Central America, the Caribbean, and Australia face below-normal precipitation, a pattern that historically triggers simultaneous food stress across multiple continents and complicates international commodity markets that India also participates in.
India's response framework has improved since earlier El Niño cycles, but gaps remain. Climate forecasting and early warning systems need strengthening so that farmers, state governments, and water managers receive actionable signals well before a deficit season unfolds. Climate-resilient agriculture, including drought-tolerant crop varieties and water conservation techniques, needs to move from pilot programmes to mainstream adoption at scale. Urban heat mitigation through green infrastructure is a related concern that the same warming episodes intensify, yet it is often treated as a separate policy silo. Public awareness of heat stress and disaster preparedness remains uneven across states.
None of these are new recommendations. A Godzilla El Niño arriving with advance notice, however, offers a rare window to act before the damage is done.
