Rainfall outlook for April 2020

APRIL rainfall is likely to be above average for Western Australia, western and southern parts of the Northern Territory, South Australia, and scattered parts of southern Queensland, New South Wales  Victoria and Tasmania.

The chance of above average April rainfall is mostly 60-75 percent for these states and regions, although there is a greater than 75pc chance of above average falls in southern WA.

Drier than average conditions are likely in along parts of Queensland’s east coast — a 60-70pc chance).

The three months from April to June are likely to be wetter than average across WA, the western and southern NT, most of SA, western and central Victoria, and north-west Tasmania  — a 60-70pc chance and a greater than 70pc chance in southern WA). The northern Cape York Peninsula in Queensland is likely to be drier than average.

Rainfall outlook for May 2020

Similarly, May to July is likely to be wetter than average for much of western, central and southern Australia  — mostly a  60-70pc chance. However, accuracy is lower at this time of year, so some caution should be exercised when using this outlook.

The rainfall outlook suggests the autumn break for southern cropping regions may occur closer to its average time this year.
