Southern Western Australia Endures Record-Driest July, Raising Crop Loss Fears

July 2026 set a new low-rain record for southern Western Australia, with the Bureau of Meteorology measuring an average of 6.86 mm statewide, the driest month since 2012 and the fourth-driest since 1900. The South West district received only 42.05 mm, far below its 112.9 mm average, while the Central West and Interior districts also fell short of normal levels. Farmers like Paul O'Meehan near Borden and Kevin O'Brien near Pingelly report that the lack of precipitation threatens both crop yields and livestock water availability, despite recent investments in dam infrastructure that have partially mitigated the shortfall.

Hydrologist Masoud Edraki explained that a dominant high-pressure ridge blocked the low-pressure systems that normally bring rain, and forecasts predict dry conditions persisting into August and September, with a potential rebound in October. The agricultural strain extends to viticulture, as Margaret River winemaker Rob Girardi warns that early vine activity could be vulnerable to late-winter storms if the dry spell continues. Overall, the region faces a critical window in which sufficient winter rain is essential to avert significant economic damage.
