As seen in the rainfall deciles map below, this above average rainfall was driven by […]
The Pacific and Indian Ocean climate drivers remain in a neutral phase, with weather around Australia continuing to be dominated by more local effects. Pacific Ocean climate driver The El Niño Southern Oscillation (ENSO) has returned to a truer neutral phase, after trending towards a La Niña-like phase during summer. Sea Surface Temperatures (SST) across […]
