Super El Nino in 2026 Tests Climate Change's Reshaping of India's Monsoon

A super El Nino is developing in the Pacific in 2026, with sea surface temperatures expected to exceed 2°C above the long-term average — a combination that scientists say will destabilise atmospheric pressure systems globally and intensify monsoon disruption in India. The India Meteorological Department is already predicting a below-average monsoon season.

El Nino years have traditionally been associated with weaker Indian monsoons, reduced agricultural yields, and heightened drought risk. In 2026, the IMD predicts neutral Indian Ocean Dipole conditions with a possible positive shift only toward the end of the monsoon season — a scenario that reduces the modulating effect that could otherwise counteract El Nino's impact. Climate change is simultaneously making extreme rainfall events more frequent: data shows India experienced close to one extreme weather event per day in recent years, with heavy rain, floods, and landslides on 68–95 per cent of days.

The paradox of India's rainfall economy deepens under a super El Nino: more rain arrives in fewer, more intense events, increasing flood risk while failing to replenish groundwater and soil moisture. Western Disturbances from the Mediterranean, traditionally a winter phenomenon, are increasingly arriving in summer and remaining active during the monsoon, causing collisions with monsoon low-pressure systems that have produced cloudbursts and flash floods in Himalayan states. The combined disruption makes agricultural planning increasingly uncertain.

India's overall water security depends heavily on monsoon outcomes: over 70 per cent of drinking water comes from groundwater recharged by monsoon rainfall, and the bulk of agricultural production remains rainfed. The author argues that India must treat every drop of rain as a strategic resource — investing in rainwater harvesting, check dams, managed aquifer recharge, and seasonal flood water banking — rather than treating monsoon outcomes as beyond policy control. Climate change has made the monsoon less predictable and more extreme simultaneously.
