An overview of the present climate in the tropical South Pacific Islands, with an outlook for the coming months, to assist in dissemination of climate information in the Pacific region.
El Niño/Southern Oscillation (ENSO)
The recent La Niña event weakened during February– March, and present conditions in the tropical Pacific are near ENSO–neutral.
Normal or below normal tropical cyclone (TC) activity is likely for most islands in the southwest Pacific during the remainder of the 2011 – 2012 season.
While ENSO is expected to be in a neutral state over the forecast period, some remnant anomalies from the event are expected to persist, including increased rainfall in a broad horseshoe-shaped zone affecting the Tropical western Pacific west of the Dateline and parts of the southwest Pacific region.
