The WMO's May 2026 El Niño/La Niña update says El Niño is developing in the tropical Pacific, with an 80% chance of onset in June to August and near-90% odds of persistence to November. Most models forecast at least a moderate event, possibly strong, with above-average temperatures expected almost everywhere.
A confirmed El Niño raises the risk of crop stress in Asia, Australia and southern Africa and of wetter conditions in parts of South America. This supports a weather premium in feed markets without a single immediate price trigger.
