The best time to visit William Creek is during the cooler, drier months from April to September. This period avoids the extreme summer heat and the possibility of heavy rainfall that can make travel challenging.
During these months, the weather is more moderate and comfortable for exploring the outback. Daytime temperatures are pleasant, typically ranging from the mid-teens to mid-twenties Celsius, and nights are cool. This climate is ideal for activities like scenic flights over Lake Eyre or exploring the Oodnadatta Track.
Couples looking for a unique outback experience will find this a great time. The clear skies are excellent for stargazing, and the milder conditions make for enjoyable evenings around a campfire.
