Season planner for Ningaloo Reef (Exmouth & Coral Bay)
Ningaloo is diveable year-round, but comfort and logistics swing with the seasons. The official Australian tropical cyclone season runs from November to April, so summer travel needs more weather flexibility. Many travelers aim for April to October for cooler hiking weather, reliable visibility, and easier boat days, while still lining up with headline wildlife: whale sharks in roughly March to July and humpback whales later in the year. Water temperatures typically range from about 20°C in winter to around 28°C in late summer, and afternoon winds often build, so early starts make a difference for snorkel and freedive sessions.
