WMO urges early action as a possibly record El Niño builds toward a year-end peak
In brief
The World Meteorological Organization (WMO) said on October 22, 2026 that the current El Niño could be unprecedented in strength, going beyond the monitoring charts used for the past four decades. The event is expected to peak toward the end of the year, and the WMO and the UN humanitarian office OCHA have jointly called for urgent, coordinated action before floods, droughts, heat and wildfires hit vulnerable communities.
Forecasts as a head start
El Niño is a natural warming of the tropical Pacific Ocean that shifts weather patterns around the world. WMO Secretary-General Celeste Saulo said a powerful El Niño does not have to become a humanitarian disaster because the science, forecasts and early warnings already exist, and what is needed now is decisive action for the most vulnerable people.
A key part of that effort is the WMO Coordination Mechanism, part of the UN's Early Warnings for All initiative. It gathers weather, climate and water information from national weather services and turns it into products designed with aid agencies, such as weekly hydromet scans and monthly climate briefings. WMO says the mechanism has delivered more than 750 tailored products since 2022 and is now helping partners prepare for El Niño's effects.
What WMO wants next
In its key takeaways, WMO said the warning window is open but will not last, that services should be designed around how humanitarian teams actually plan and decide, and that national weather services remain the trusted voices. It also called for more member countries to take part and for steady funding to grow the work.
VSH take: El Niño headlines can sound scary, but the useful part of this story is how much warning the world gets this time. For readers, it is a good reason to follow your national weather service and check seasonal outlooks before planning winter travel.
