Short-term rainfall deficiencies increased in south-eastern Australia as large areas received below-average April rainfall, according to the Australian Bureau of Meteorology drought report issued yesterday.
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.
The first quarter of 2018 has been marked by an extended period of particularly dry weather for much of mainland south-eastern Australia, chart 2.
January to April was the seventh-driest such period for south-eastern Australia as a whole.
