Wheat Belt conditions are severely challenging with rainfall at just 31% of average and critically low soil moisture at 5.4%, significantly worse than the WA state average of 6.2%. These dry conditions pose substantial risks to the region's wheat, barley, and canola crops, with inadequate moisture for germination and early crop establishment. The sub-region's composite score of 26 reflects much higher stress than the state average of 35, with fire risk elevated given WA recorded 7,370 hotspot detections over seven days.
