Introduction

Sea surface temperatures anomalies in the Equatorial Pacific are maximum around the international Dateline and reflect weak El Niño conditions in March 2015.

Tropical rainfall and SST outlook: April to June 2015

The dynamical model forecasts indicate that the central equatorial Pacific is likely to experience above normal rainfall in April – June 2015. In contrast, regions in the western Pacific south of the Equator, as well as the south eastern Pacific are expected to experience reduced rainfall. Below normal rainfall is forecast for Fiji, the Marquesas, Papua New Guinea and Vanuatu.
