Scientists Warn of Mega El Niño Probability in 2026-27; Advise Preparedness
Research points to a potential mega El Niño as Pacific Ocean temperatures rise rapidly; the global weather system may face extreme heat, weak monsoons and severe climate impacts by 2026-27
April 22, 2026 - Researchers studying the Pacific Ocean say that recent model tests have shown a rapid increase in sea surface temperatures, which is a key indicator of El Niño formation. Scientists have even said that if the current trend continues, it could take the form of a mega or super El Niño.
El Niño is part of the El Nino-Southern Oscillation (ENSO) climate cycle in which waters in the central and eastern Pacific Ocean become warmer than normal. This changes wind and rainfall patterns. It usually weakens the monsoon.
After analysing seasonal patterns, scientists have indicated such signals. According to this, the rapidly increasing temperature in the Pacific Ocean is pointing toward a mega El Niño, which, if it strengthens, will severely impact the global weather system. By 2026-2027, the world may face record-breaking heat, weak monsoons and extreme weather conditions. Places like Australia, southern and central Africa, the Amazon basin and India will become at high risk for intense heat, drought and wildfire risks.
The last time when the world faced a similar effect was in 1877 when the impact of a super El Niño led to low rainfall, heat and drought resulting in the death of about 4% of the world’s population.
Experts say that this time El Niño could be more dangerous than before, because climate change conditions were not as severe back then in 1877–78 which is considered one of the deadliest climate event periods in history. At that time, El Niño caused severe heat, prolonged drought, crop destruction, famine and starvation across most parts of Asia, Africa and Latin America. During this period, millions of people died, which is estimated to be about 4% of the global population at that time.
Researchers say India should, in particular, be worried because the country relies heavily on the monsoon for its agriculture and overall prosperity. El Niño is known to cause drought, crop failure and heightened health risks. If the El Niño effect is seen in 2026, then India will be in for extreme heat conditions and below-average rainfall across the northern, central and eastern parts.
Scientists, however, say that while it is still early to forecast mega El Niño, yet the signals cannot be ignored and the country needs to be prepared.
