The best time to go to Rawlinna is during the cooler months, specifically from May to October, to avoid the extreme heat of the Western Australian desert.
During this period, the daytime temperatures are more pleasant, typically ranging from 15°C to 25°C, making outdoor activities and exploring the vast Nullarbor Plain much more comfortable. The nights can still be cool, so packing layers is advisable.
This timeframe is particularly good for those interested in the great experience of the Trans-Australian Railway. The journey across the Nullarbor is best enjoyed when the weather allows for comfortable viewing from the train or for brief stops along the way.
Families might find these months ideal for a less strenuous adventure, as the milder climate is more forgiving for children.
