April-June 2020 rainfall outlook
Wetter April to June for western and southern Australia
April rainfall is likely to be above average for WA, the western and southern NT, SA, and scattered parts of southern Queensland, NSW, Victoria and Tasmania (mostly 60–75% chance, greater than 75% chance in southern WA). Drier than average conditions are likely in along parts of Queensland’s east coast (60–70% chance).
The three months 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 northwest Tasmania (60–70% chance, greater than 70% chance in southern WA). Northern Cape York Peninsula in Queensland is likely to be drier than average.
Similarly, May to July is likely to be wetter than average for much of western, central and southern Australia (mostly 60–70% 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.
