Scientists have confirmed an 82% chance of a Super El Niño developing between May and July 2026, with a 96% likelihood it will persist through winter 2026-27. This climate event, characterized by unusually warm Pacific Ocean waters, is expected to disrupt global weather patterns, trigger extreme heat, and exacerbate droughts and flooding in vulnerable regions.
Immediate Impacts and Core Facts
The World Meteorological Organisation (WMO) and NOAA predict this El Niño will be among the strongest on record, with sea surface temperatures rising significantly in the central-eastern Pacific. The event is expected to raise global average temperatures by up to 3°C (5.4°F), intensifying heatwaves and altering rainfall patterns. Drier conditions are forecast for Central America, northern South America, the Caribbean, Australia, and parts of southern Asia, while increased rainfall is expected in southern South America, the southern U.S., the Horn of Africa, and central Asia.

Economic and Environmental Consequences
The National Oceanic and Atmospheric Administration (NOAA) warns that coral reefs—already under stress—face widespread bleaching due to warmer ocean temperatures. This could mark the fifth global bleaching event in recorded history, further threatening marine ecosystems. Meanwhile, food prices in the UK and other importing nations may surge as El Niño disrupts crop yields for bananas, rice, tea, coffee, and fresh fruit, adding hundreds to grocery bills.
Scientific and Policy Responses
Researchers emphasize that climate change is amplifying El Niño’s effects, making extreme weather events more frequent and severe. The UN has urged countries to treat this as an urgent climate warning, calling for preparedness measures. However, some experts argue that natural variability still plays a role, and not all impacts can be directly attributed to human-induced warming.
Global Preparedness and Mitigation Efforts
Governments and agencies are monitoring conditions closely to issue early warnings for droughts, floods, and heatwaves. The WMO advises nations to strengthen disaster response plans and adapt agricultural practices to mitigate food shortages. Meanwhile, environmental groups are pushing for accelerated climate action to reduce long-term risks.
