Total rainfall for Australia was the eighth-lowest on record for April, chart 1. For southern Australia as a whole, rainfall was the third-lowest on record for April.

Exceptionally warm weather during April exacerbated the effect of low rainfall

Lower-layer soil moisture was below average for April across eastern South Australia, New South Wales, and Victoria.
