Weekly Australian Climate, Water and Agricultural Update, 24 July 2025

Key issues

• In the week ending 23 July 2025, frontal systems brought rainfall totals of up to 100 millimetres to parts of southern Australia, and up to 50 millimetres in the east. High-pressure systems kept much of the remainder of Australia largely dry.
  • Rainfall was variable across cropping regions, with much of Western Australian and Queensland regions, as well as parts of New South Wales seeing 5-50 millimetres. Meanwhile western areas of South Australia and eastern areas of Victoria received 5-15 millimetres.
  • The ongoing lack of rainfall across the drought affected Mallee regions of South Australia and Victoria continues to present a downside production risk for winter crops.
• Over the coming eight days, rainfall is expected across much of Australia, with southern and eastern regions seeing high rainfall totals.
  • Cropping regions in Queensland, South Australia and Victoria are expected to record between 25-50 millimetres of rainfall, with isolated areas seeing up to 100 millimetres. Falls of between 15-50 millimetres are expected across New South Wales. Western Australian cropping regions are likely to see lower rainfall of 10-50 millimetres. If realised, this should provide timely moisture to support the establishment and growth of winter crops across most growing regions.
• The national rainfall outlook for August to October 2025 indicates an increased probability of above median rainfall across much of central and eastern Australia. Most western regions are likely to see close to average rainfall.
  • If realised, the expectation of average to above average August to October 2025 rainfall across most winter cropping regions is likely be sufficient to support the growth and development of winter crops.
