March through May and September through November are deemed to be the best time to visit South Australia. Fall boasts a low possibility of rains and an excellent chance to explore Simpson Dunes. Spring is known for a relatively slow tourist season when the air warms up; the prices are affordable and wildlife is easy to observe. This period is perfect for hitting Stuart Highway or Birdsville Track and exploring the state. June through August in SA is never very cold. During these months, the state offers fewer tourists, the cheapest accommodation, and a perfect whale watching experience. However, winter also has the most precipitation. Peak season in South Australia runs from December to February. Summer months bring the heat, bright sun, and clear skies—fantastic conditions for chilling on the beach or strolling around Umpherston Sinkhole. Just don't forget to grab a wide-brimmed hat.
