Koolan Island 12-month Rainfall ForecastAprMayJunJulAugSepOctNovDecJanFebMar20242025567988789679105012 - 34 - 78 - 910Well below normalBelow normalNear normalAbove normalWell above normalIssue Notes - Issued Apr 23
ENSO status: Inactive/Neutral. El Niño ended. IOD status: Neutral, becoming strongly positive. SAM status: Leading to neutral and returning positive. The El Niño Southern Oscillation (ENSO) is presently in an inactive phase, for the first time since August 2021. Ocean cooling continues over the eastern Pacific Ocean as sea surface temperatures approach near-normal conditions. Warmer than normal waters are present across the western Pacific Ocean, including the Coral Sea with added moisture and humidity to influence weather conditions in the eastern regions of Australia. The atmosphere continues to be firmly neutral after weakening early in the year with 3 out of 7 global models forecasting a La Niña to develop this coming winter season. A neutral ENSO typically has no significant impact on Australian rainfall during winter. The Indian Ocean Dipole (IOD) is in a neutral phase, although record-high ocean temperatures across the northwest Indian Ocean have the IOD index just tipping into a positivethreshold value. Persistent southeasterly winds over the eastern Indian Ocean during the previous month are forecast to ease with below-average wind speeds to develop off northwest Australia and the eastern Indian Ocean during the winter season. All international models are suggesting the IOD will strengthen into a strong positive phase over the next 2-3 months, with significant upwelling to start near Indonesia possibly following May. A positive IOD reduces the number of northwest cloudbands that cross Australia during winter and spring, thus reducing rainfall across central and southeastern parts of Australia. The Southern Annular Mode (SAM) is currently positive (mid-April) with the outlook favouring a neutral phase forecast in May and then the likelihood of returning to a positive phase during winter. A positive SAM increases easterly winds, increasing rainfall and thunderstorm activity in the east. A positive SAM also reduces the impact of cold fronts and decreases the rainfall over southernAustralia. Rainfall outlooks are showing above-average rainfall over winter for WA and central and northern SA, and eastern regions of QLD and NSW. Conversely, below-average rainfall is expected for western TAS, southern SA, and most of VIC.
