The WMO says the weak La Niña that formed in December 2024 is likely to be short-lived. It gives a 60% chance of a shift to ENSO-neutral during March-May 2025, rising to 70% for April-June, and a negligible chance of El Niño developing through June.
A quick return to neutral lowers the risk of drought in key exporting regions such as Argentina, southern Brazil and Australia. That reduces the case for a weather-driven supply shortfall in grains and oilseeds.
