# IRI – International Research Institute for Climate and Society | August Climate Briefing: La Niña Seeming More Likely

> IRI reported that tropical Pacific sea-surface temperatures in mid-August were near the threshold for weak La Niña. Its model runs give a 55-60% probability of weak La Niña for the September-November through November-January seasons, and the official ENSO forecast now carries a La Niña watch.

## Why it matters

Rising La Niña odds point to dry risk for South American crops and a possible shift in US and Canadian growing conditions, which supports prices for corn, soybeans and wheat.
