Climate in Western Australia
Western Australia is huge, so the climate changes a lot from one region to another. The state is usually divided into three main zones: tropical in the north, semi-arid in the interior and Mediterranean in the south. The tropical north has a dry season from April to September and a wet season from October to March, when the weather becomes very humid and heavy rain is common. The interior is hot, dry and mostly desert. The south has warm, dry summers and mild, wetter winters. Perth sits in this southern zone, and strong afternoon sea breezes help cool the hot summer days. Humidity is generally low, and July is usually the wettest month.
