The peak period for rainfall gradually shifts from November to April in the Kimberley to a maximum between May and October in the south-west. Temperatures also vary greatly over this wide expanse. Daytime maxima above 40 C are common in inland parts during the summer, but may drop below 10 C in southern areas in winter. Through the cooler months, overnight minima below 5 C occur frequently in the south and inland. Frosts are possible, and snow occasionally falls in the far south, particularly on the Stirling Range.
