Temperate climate with warm summers and cool winters. The average yearly rainfall in the south of the bioregion is quite different to that in the northern area. Some areas in the south receive up to 600 mm of rain, while areas in the north of Eyre Peninsula receive about 350 mm. Most of the rainfall occurs in winter.
