The best time of year to visit Fraser Island is during the Australian winter and spring months, from June to October. During this period, the weather is generally mild and dry, with temperatures ranging from 14°C to 25°C (57°F to 77°F). This is an ideal time for camping, swimming, and exploring the island's many attractions without the intense heat or humidity of the summer months. Additionally, this is the prime time to spot humpback whales during their migration along the island's coast.
