Is your local community doing enough to prepare for the projected weather impacts of El Niño?
The World Meteorological Organization has released a new climate outlook projecting that the current El Niño event will reach record-breaking intensity by late 2026. Experts anticipate sea surface temperatures in the tropical Pacific could rise 3.8°C above average, driving significant weather disruptions globally.
Why it matters
This forecast is designed to help governments and humanitarian groups anticipate risks and protect vulnerable populations from the projected surge in extreme weather events. The WMO is working with the UN to ensure climate data informs practical, life-saving decision-making.
The WMO warns of tropical Pacific sea surface temperatures rising 3.8°C above average, a figure exceeding monitoring benchmarks used over the past four decades. This shift is expected to catalyze a surge in extreme weather events as the El Niño peaks.
The players
World Meteorological Organization
This specialized agency of the United Nations is responsible for promoting international cooperation on atmospheric science and meteorology.
United Nations Office for the Coordination of Humanitarian Affairs
This UN body is tasked with bringing together humanitarian actors to ensure a coherent response to complex emergencies and natural disasters.
The details
As the event intensifies, global regions face varying risks including flood threats in East Africa and the Northwest US, while Southeast Asia braces for increased wildfire risks and smoke-haze. Conversely, Southern Africa, Central America, and the Amazon are expected to face heightened drought conditions.
Timeline
October-December 2026: East Africa faces elevated risks of heavy rainfall and flooding.
November 2026: Drier conditions are expected to develop across Southern Africa.
November 2026-January 2027: Tropical Pacific sea surface temperatures are projected to peak at 3.8°C above average.
December 2026: The El Niño event is expected to reach its maximum strength.
Seasonal Patterns
This report marks a departure from historical norms as current projections exceed the thresholds established by the climate monitoring charts used for the past four decades. The intensification represents a significant shift in the behavior of contemporary El Niño events.
Communities in high-risk zones like East Africa should monitor local emergency alerts for flood preparedness, while regions facing wildfire risks should prepare for air quality advisories. Governments and aid agencies are being urged to coordinate anticipatory action to mitigate the impacts of the projected extreme weather.
The takeaway
The projected 3.8°C rise in sea surface temperatures underscores the necessity for proactive regional climate planning to handle potential food and water security challenges. Households in affected areas should stay updated with localized warnings as the El Niño event approaches its December peak.
