The weather in Australia’s southwest is unlike any other region in Western Australia. According to the local Aboriginal culture, instead of your ordinary summer, autumn, winter, spring – this region has six varying seasons that range from hot and dry to cold and wet and everything in between.
The original inhabitants of this land were nomadic hunters who followed this six season calendar to navigate the varied weather and wildlife patterns, and when you visit you will see why! While you may not be hunting, planning around this traditional seasonal calendar is the best way to get an accurate representation of the weather during different months of the year so you know what to pack, and when to plan your adventure to experience the top things to do on Rottnest Island.
It is also worthwhile checking out Western Australia’s nature’s calendar to see what natural events and attractions occur at different times of the year, such as whale watching, seals and sea lions, manta rays and so on.
When it comes to best time to visit Rottnest Island, there really is no ‘right’ time – only preferences. If you are dreaming of a summery snorkel filled adventure, I would recommend travelling here in February-March when the weather is warm and the water is inviting, but the deep heat of summer has started to dissipate. However, if you don’t mind the cooler water termperatures, October-November is a great time to catch a glimpse of the ‘humpback highway’ migration and the wildflowers in bloom.
