For April- June 2023, the models unanimously agree on above normal raindall for most of FSM, central Marshall islands, the southeast of PNG's EEX, southern Solomon Islands and Vanuatu. There are also unaimous in showing that below normal rainfall is likely or very likely for southern parts of central and eastern Kiribati, Tokelau, northern Cook Islands and northern French Polynesia.

La Nina has weakened in the tropical Pacific Ocean and is likely near it end. Sea surface temperatures (SST) in February 2023 were cooler than average across much of the tropical Pacific Ocean, extending from around 165°E in a broadening wedge to the South America coastline.

La nina continues in the tropical Pacific, but oceanic indicators (sea surface temperatures, SSTs) have weakened since their peak during spring 2022.

La Niña continues in the tropical Pacific and models suggest a return to ENSO-neutral SSTs in January or February 2023.

Key atmospheric and oceanic indicators of ENSO show an established La Niña. Models indicate this La Niña event is likely to decline early in the southern summer, with a return to ENSO-neutral (neither La Niña nor El Niño) early in 2023

The 2021-22 La nina event has ended. However, observations and cimate model outlooks suggest La nina may reform later in 2022. Most climate models surveyed by the Bureau indicate ENSO is likely to remain neutral through the southern hemisphere winter.

The 2021-2022 La Niña event has weakened slightly in the tropical Pacific over the past fort-night. Climate outlooks indicate a return to neutral El Niño-Southern Oscillation (ENSO) levels-neither La Niña nor El Niño-late in the southern hemisphere autumn (April to May 2022).
