South Australia is a vast State and temperatures can vary dramatically from region to region. Different trails are suitable at different times of the year, and it's important to check weather conditions before you set off.
South Australia has a mediterranean climate with conditions generally cool to mild with frequent rain in the winter months (June to August) and warm to hot and dry in the summer and early autumn (December to April). Some trails are closed during the high fire risk months of November and December to the end of March/April.
Autumn to Spring (April to November)
This is a good time of year to visit most regions. However, the Mount Lofty Ranges can experience some rainy, winter days at this time of year and maximum temperatures often hover around 10 degrees centigrade. In the northern part of the State days are generally fine and sunny, but nights can reach 0°C.
Summer (December to March)
Temperatures often rise above 35 degrees centigrade during summer, particularly higher in the Flinders Ranges and Outback. We don't recommend taking a long trail on hot days, as there is a considerable risk of heat exposure and dehydration.
