The World Meteorological Organization (WMO) has issued a warning that a La Niña phase could develop in the coming months, marking a potential shift in global weather patterns after several months of neutral ENSO (El Niño–Southern Oscillation) conditions across the Pacific Ocean.
Increasing Likelihood of La Niña Conditions
According to the WMO’s latest climate update, sea surface temperatures in the central and eastern Pacific have begun to cool slightly — a trend that could evolve into a full La Niña event by early 2026 if it continues. Current climate models indicate a 60% probability of La Niña conditions forming before mid-next year.
“La Niña typically brings wetter conditions to parts of Southeast Asia, Australia, and East Africa, while contributing to drier, warmer weather in southern South America and parts of the U.S.,” said Dr. Petteri Taalas, WMO Secretary-General. “Monitoring these shifts is critical for agriculture, disaster preparedness, and water management planning worldwide.”
Global Impacts and Climate Implications
This potential transition comes after an intense El Niño event in 2023–2024, which triggered severe droughts and heatwaves across parts of Africa and South America. While a La Niña phase could help rebalance global temperature trends, meteorologists warn that it may also intensify regional climate extremes.
WMO Calls for Early Preparedness
The WMO has urged governments and humanitarian agencies to strengthen early preparedness efforts, emphasizing the role of seasonal forecasting and early warning systems in mitigating the impacts of climate variability. As global temperatures continue to rise, understanding and anticipating ENSO cycles remains crucial for managing agriculture, disaster response, and resource allocation.
