# IRI – International Research Institute for Climate and Society | April Climate Briefing: La Niña Transitions Out, Neutral Next

> The IRI April climate briefing reports that equatorial Pacific sea-surface temperatures have warmed from La Niña into neutral territory, with the Niño3.4 anomaly averaging -0.28ºC over four weeks. Subsurface waters are also warming, and models suggest this warmth will reach the surface in coming months.

## Why it matters

A shift from La Niña to neutral reduces the odds of drought-prone conditions in key South American and other exporting regions, a modestly bearish factor for grain and oilseed risk premiums over the coming months.
