NIWA's seasonal outlook says ENSO-neutral conditions persisted in the tropical Pacific in August 2017, with some indicators leaning toward La Niña. International guidance gives a 65% chance of neutral conditions for September to November 2017.
Neutral ENSO with a slight La Niña tilt generally implies no major El Niño-driven drought or flood risk for key grain and oilseed origins over the coming months, which keeps weather premium limited.
