From its tropical north to temperate areas in its south-west corner, Western Australia experiences a variety of climatic conditions.
With distance from the coast, rainfall decreases, and temperature variations are more pronounced.
Perth averages eight hours of sunshine per day and 118 clear days per year. Mean monthly maximum temperatures range from 17ºC in July to 30ºC in February. Even in the coldest months, minimum temperatures rarely fall below 5ºC. Most of its 802mm annual rainfall occurs in the winter months
