The El Niño weather phenomenon is expected to intensify through 2027 and could become the strongest ever recorded, according to the World Meteorological Organization. The WMO says there is a near 100% probability that El Niño will persist through February 2027, driven by exceptionally warm Pacific Ocean temperatures.
El Niño Could Reach Unprecedented Strength
WMO Secretary General Celeste Saulo said that if the current trajectory continues, the phenomenon could exceed anything recorded since systematic monitoring began four decades ago.
El Niño is expected to peak toward the end of 2026, but its effects could continue well into 2027.
Global Weather Risks
A very strong El Niño can significantly alter rainfall and temperature patterns around the world. It can contribute to extreme weather events, including intense rainfall, droughts and typhoons.

The prolonged phenomenon could also contribute to higher global temperatures in 2027.
Food Crisis Already Emerging
The effects are already being felt in tropical regions. This year’s El Niño has affected soft commodities and contributed to a severe food crisis across Central America’s Dry Corridor.
The phenomenon’s impact on rainfall and temperatures could create further challenges for agriculture and other climate sensitive sectors.
WMO Strengthens Preparedness
The WMO said it is increasing preparedness and early warning efforts ahead of the expected intensification.
The organisation plans to work with the United Nations and humanitarian partners to provide climate information to sectors including agriculture, health, energy and water resources.
Why It Matters
The potential scale of this El Niño means its consequences could extend well beyond the Pacific. Changes in rainfall and temperatures can affect food production, water availability, energy systems and disaster risks across different regions.
The possibility of the strongest El Niño ever recorded also increases the importance of early warnings and preparation before the phenomenon reaches its expected peak.
Key Stakeholders
The World Meteorological Organization is leading international monitoring and preparedness efforts. United Nations agencies and humanitarian organisations will be important in responding to weather related risks, while agriculture, health, energy and water sectors face direct exposure to the phenomenon’s effects.
What’s Next
El Niño is expected to intensify and peak toward the end of 2026, with its effects continuing into 2027. The WMO will continue monitoring Pacific Ocean temperatures while strengthening early warning and preparedness measures.
Analysis
The significance of the WMO warning lies in the combination of unprecedented intensity and prolonged duration. El Niño is a natural climate phenomenon, but an exceptionally strong event can amplify existing vulnerabilities by disrupting rainfall, temperatures and food production across multiple regions.
The fact that the WMO is forecasting a near 100% likelihood of persistence through February 2027 gives governments and humanitarian organisations an unusually clear warning window. The immediate challenge is therefore not simply predicting the phenomenon, but using that certainty to prepare agriculture, water, energy and health systems for potentially severe disruptions.
If the current trajectory continues, the event could become a major test of global disaster preparedness and early warning systems, particularly in regions already experiencing food and climate related pressures.
