Drier April to June likely for southern two-thirds of Australia
APRIL is likely to be drier than average in the central, south and southwest of Australia, but wetter for eastern NSW, southeast Queensland and far northern Australia.
That’s according to the latest Bureau of Meteorology Seasonal Climate Outlook statement, released today.
April to June rainfall is likely to be below average over the southern two-thirds of Australia, except the east coast and most of Tasmania.
Rainfall is likely to be above average for the far north.
Outlooks are influenced by warming of tropical Pacific sea surface temperatures, a cooler than average eastern Indian Ocean, and some cooling of the Coral Sea.
Historical outlook accuracy for April to June is generally moderate to high over most of Australia, but low in Tasmania and small patches across the south. See map for more detail.
