The IRI's November 2018 ENSO Quick Look reports El Niño-level sea surface temperatures in October with subsurface waters continuing warmer than average, though atmospheric patterns were mostly neutral. The official CPC/IRI outlook gives an 80% chance of El Niño during winter and 55-60% into spring 2019, and an El Niño watch is in effect.
A developing El Niño raises the risk of drought in Australia, Southeast Asia and parts of South America, which could cut crop output and firm prices for grains, oilseeds and palm oil. Traders are likely to price in some weather premium ahead of the 2019 season.
