South Australia's climate is marked by hot, dry summers and mild winters. Therefore, spring (September to November) and autumn (March to May) are ideal for hiking, with comfortable temperatures. However, beware of occasional heatwaves in autumn.
The coastal regions stay relatively cool in summer, offering a respite. Ensure you're prepared for sudden weather changes, particularly in the Adelaide Hills.
Winter hiking can be rewarding but also challenging due to rainfall and lower temperatures, particularly in the Flinders Ranges. Always check weather forecasts via the Bureau of Meteorology
