A CGSPace presentation dated October 18, 2023 says the El Niño has been in place since late May 2023 and is already strong, with peak intensity expected November to January. It also notes a positive Indian Ocean Dipole is underway, which can amplify the effects.
The event is likely to persist through March to May 2024, with a 3 in 10 chance of a historically strong event.
A strong, persistent El Niño combined with a positive Indian Ocean Dipole raises the risk of crop shortfalls in Australia, Southeast Asia, Southern Africa and Latin America. That supports feed grain and wheat prices into 2024.
