General Information

Perth Weather

December is the start of the summer season in the southern hemisphere, which makes Perth an ideal destination to escape the cold winters on the northern half of the globe.


Perth is located on the coast of the Indian ocean and has a hot-summer Mediterranean climate, similar to Italy, Spain, southern France, Morocco, Lebanon, and Turkey.


On most summer afternoons a cool sea breeze, known locally as the Fremantle Doctor, blows from the southwest, providing relief from the hot north-easterly winds.


Temperature in December: average high 29°C (84°F), average low 16°C (61°F).
