Bungle Bungles weather and climate
While the below table indicates average temperature, rainfall and other weather factors, we recommend visiting the Bureau of Meteorology for up-to-date weather information before your trek.
Thanks to a wet season during summer and parts of autumn, Purnululu National Park is lush, green and not too hot during winter. June and July are the prime trekking months in the area, when daily temperatures average at about 30 degrees, and evenings can be cooler, dropping to around 15 degrees. Evenings in the Bungle Bungles have been known to drop dramatically when a cold easterly wind blows – sometimes to close to zero, so while we generally recommend sleeping under mosquito nets, it’s advisable to bring layers so that you can warm up when / if temperatures drop in the evening.
Due to the small window of pleasant weather, visitors may find that they need to book ahead for trips in June and July. Unlike other seasons, winter weather is fairly predictable and you can be (almost) guaranteed clear blue skies day after day, with almost 0% chance of rain!
By October, temperatures in Purnululu are starting to hit the late 30’s – and even up to 50 on some days. With such constant heat, waterholes have dried up by now and the landscape is brown, dusty and hot! Towards the end of spring is the build up to the wet season, with big storm clouds on the horizon and strong winds. We do not run any trips during spring as these months are too hot and unsuitable to trek in.
Summer brings with it rain, rain and more rain! With such high temperatures in the late 30’s combined with the high rainfall, the humidity in the region can be incredible uncomfortable. Many tourist shops close during summer as highways and major roads get flooded and cut off. We do not run any trips during summer as these months are too wet, hot and unsuitable to trek in.
Autumn is the tail end of the wet season, so while the rain has eased off a little bit, the temperatures are still high enough to make the area’s humidity unbearable. Most unsealed roads are still closed from the wet season rains, and accessibility is still very limited. We do not run any trips during autumn as these months are too hot and unsuitable to trek in.
