El Niño expected to intensify into very strong event through early 2027
The World Meteorological Organization (WMO) and United Nations officials have issued urgent warnings regarding a rapidly intensifying El Niño event. Experts state the phenomenon is firmly established and is expected to reach a ‘very strong’ intensity in the coming months, potentially becoming the strongest event recorded in the last 40 years of monitoring.
Forecasts indicate a nearly 100% probability that the event will persist through February 2027. This intensification is driven by exceptional warming in the tropical Pacific Ocean, where sea surface temperature anomalies have significantly exceeded historical averages. The WMO notes that the level of agreement between various climate models is the highest seen in its 50-year history.
The global implications are severe, with risks including extreme heat, prolonged droughts, and intense flooding. Specific regional concerns include agricultural impacts in Central America and South Asia, and extreme weather in Latin America and Australia. UN Secretary-General António Guterres warned that the planet is entering a ‘danger zone’ of extreme weather, noting that while El Niño is a natural phenomenon, it will exacerbate the effects of global warming, which is nearing the 1.5 degree Celsius threshold.
