Early rainfall onset likely for most of northern Australia

An early rainfall onset for the 2021–22 season is likely across most of northern Australia. Most of Queensland and the NT have a greater than 70% chance of an early rainfall onset, with parts of central and south-western Queensland having a greater than 80% likelihood. Areas of WA bordering the NT, and large parts of south-east Queensland have more than a 60% likelihood, while the remaining areas of WA have roughly equal chances of an early or late rainfall onset.
The northern rainfall onset outlook gives an indication of whether the first significant rains after the 1st September are likely to be earlier or later than median.
