Global Impacts Expected as El Niño Conditions Likely to Develop by Summer
US · Published Jun 4, 2026
El Niño conditions are expected to return in the coming months, with an 80% likelihood of forming between June and August 2026 and a 90% chance by November, according to the World Meteorological Organization (WMO).
This weather phenomenon, characterized by warming Pacific Ocean waters, is part of a recurring global cycle that significantly influences weather patterns worldwide.
The WMO has indicated that sea-surface temperatures in the central-eastern equatorial Pacific are nearing El Niño thresholds, with atmospheric indicators also aligning.

Why It's Important?

The potential El Niño event poses significant risks globally. Wetter conditions in the southern United States and other regions could lead to flooding, while drier conditions in areas like Central America and Australia may exacerbate droughts. Increased cyclone activity in the Pacific could threaten coastal communities, while a quieter Atlantic hurricane season may offer some relief. Heatwaves are also expected to intensify, compounding existing climate challenges. Vulnerable populations, particularly in regions prone to extreme weather, are at heightened risk. The WMO has stressed the importance of early warnings and seasonal forecasts to mitigate these impacts, especially in sectors like agriculture, water management, and energy.
