As India struggles through rising temperatures and severe heatwaves, meteorologists are closely watching a developing climate event in the Pacific Ocean that could shape the country future for months ahead. Scientists warn that the possible return of El Niño during 2026 may weaken the southwest monsoon, raising concerns over agriculture, water supplies, food prices and the rural economy.
The southwest monsoon delivers nearly 70 percent of India’s annual rainfall and remains the backbone of farming across the country. But experts say warming sea temperatures in the Pacific Ocean are beginning to signal the emergence of El Niño, a global climate pattern often associated with hotter and drier weather conditions in Asia.
Climate specialists explain that El Niño develops when sea surface temperatures in the central and eastern Pacific Ocean become unusually warm. This disrupts atmospheric circulation and weakens the monsoon winds that normally carry moisture toward the Indian subcontinent.
According to weather experts, the current El Niño is still evolving and its full intensity remains uncertain. However, forecasts from international climate agencies suggest there is a strong possibility that the phenomenon may continue through late 2026 and into early 2027.
Meteorologists also warn that not all El Niño events behave the same way. A “Modoki El Niño,” where warming remains concentrated in the central Pacific, is considered especially dangerous for India because it can suppress rainfall more severely than traditional El Niño patterns.
Despite the concerns scientists say there is still room for cautious optimism. Another climate system known as the Indian Ocean Dipole or IOD, may partially offset some of El Niño’s drying effects if it turns positive later in the monsoon season. A positive IOD strengthens moisture transport from the Indian Ocean toward India and has previously helped rescue weak monsoon years.
History also shows that El Niño does not always result in drought. India received above normal rainfall during the powerful 1997-98 El Niño because of a strong positive IOD. Similar outcomes were seen during some other past El Niño years as well.
Still, experts believe climate change is making weather patterns more unpredictable and extreme. Rising global temperatures are intensifying heatwaves, altering rainfall distribution and increasing the chances of sudden weather shocks. Scientists warn that even if overall monsoon rainfall remains close to normal, uneven rain distribution could still damage crops and disrupt agriculture.
Environmental researchers say India may face additional challenges if rainfall remains weak, including water shortages, lower reservoir levels, rising vegetable and edible oil prices, pressure on electricity demand and increased risk of forest fires.
The India Meteorological Department has already predicted below-normal monsoon rainfall for 2026, estimating seasonal rainfall at around 92 percent of the long-term average. Experts say this forecast makes preparedness extremely important.
Authorities are encouraging states to strengthen drought management plans, improve water conservation systems, promote drought-resistant crop varieties and prepare farmers for changing weather conditions. Health officials are also advising people to remain cautious as prolonged heatwaves continue to affect several parts of the country.
Scientists stress that El Niño should be viewed as a warning sign rather than a certainty of disaster. Advances in weather forecasting now provide governments and farmers with more time to prepare for potential climate disruptions.
For millions of Indians whose livelihoods depend on seasonal rains, the coming weeks will be critical as the Pacific Ocean continues to evolve and the monsoon inches closer to the subcontinent.
