Summer (November to March) are known for hot, dry days and mild to warm dewless nights. Summer is typically dry but at times tropical cyclones can develop off the north west coast of WA. As these cyclones cross the coast and weaken a rain bearing depression can move over the Murchison region. The rain can vary from light drizzle to widespread heavy falls. Wooleen Station closes for tourism over the summer months due to this intense heat and sometimes flooding rains.
Autumn/Winter/Spring (April to October) is known for mild days and cool to cold nights. Winter is marked with the increase of cold frontal activity located well to the south of WA. Only the strongest fronts make it to the Murchison region bringing widespread winter rainfall. Frosts can occur occasionally during the winter months.
