Australia Weather

Australia has the driest climate on the earth, making for a warm, sunny vacation all year long. The seasons are opposite of the northern hemisphere—winter is in June, July, and August and summer is in November, December, and January. In the Australian winter, the north still stays quite temperate. However, the mountains in the south provide for some nice skiing. So if you fill the urge to ski in the middle of July, head on down to the land down under.
