The United Nations World Meteorological Organization announced an 80% probability [1] that an El Niño event will occur between June and August 2026.
This forecast is critical because the phenomenon interacts with the atmosphere to trap more heat, compounding the effects of existing global warming. A moderate-to-strong event threatens to destabilize weather patterns and increase the frequency of climate-related disasters.
The agency issued the warning on June 2 [2]. A spokesperson for the World Meteorological Organization said that a phenomenon of moderate or possibly strong intensity [3] could lead to an increase in global temperatures.
This atmospheric shift does not happen in isolation. The UN Secretary-General said that El Niño will throw "gasolina al fuego" — or gasoline on the fire — of a planet that is already warming and will worsen extreme phenomena.
The organization noted that the specific risk period spans from June through August [1]. The interaction between the ocean and the atmosphere during this window intensifies the trapping of heat, which elevates the risk of severe droughts, and flooding in various regions.
Climate experts emphasize that the intensity of this cycle determines the scale of the impact. Because the current forecast suggests a moderate-to-strong level [3], the potential for record-breaking heat is significantly higher than during neutral years.
“There is an 80% probability that an El Niño episode will be established between June and August 2026.”
The convergence of a strong El Niño with long-term anthropogenic climate change creates a compounding effect. While El Niño is a natural cycle, its ability to spike global temperatures means that 2026 could see a surge in extreme weather events, putting additional pressure on global food security and disaster response infrastructure.
