The United Nations World Meteorological Organization is forecasting a potentially strong El Niño event that could increase extreme weather risks worldwide [1, 2].
This climate pattern is significant because it alters atmospheric circulation on a global scale. When combined with long-term climate warming, these events can amplify heat waves and disrupt precipitation patterns across multiple continents [1, 3].
According to a United Nations warning published June 2, 2026, the phenomenon is developing in the central and eastern equatorial Pacific Ocean [2]. Climate expert Dr. Herman Van Niekerk, a senior lecturer, said the event may be classified as a "super" El Niño due to its projected intensity [1].
These events typically last between nine and 12 months [3]. While the warming is currently developing, the strongest impacts are expected to be felt during the fall or winter of 2026 [4].
El Niño occurs when sea-surface temperatures in the central and eastern Pacific Ocean rise periodically [1, 3]. This shift in ocean temperature disrupts the normal flow of air and moisture, creating a ripple effect that impacts weather in regions far from the Pacific [3, 4].
Experts are monitoring the speed of this development, as some reports suggest the event is arriving faster than previously expected [4]. The resulting weather disruptions often include severe droughts in some regions and heavy flooding in others [1, 3].
“A potentially strong (sometimes called a “super”) El Niño event is forecast.”
The emergence of a 'super' El Niño during a period of existing global warming creates a compounding effect. This suggests that 2026 may see record-breaking temperatures and more volatile weather patterns than a standard El Niño year, challenging the disaster preparedness and agricultural stability of vulnerable regions.
