South Australia is a year-round destination and the best time to travel South Australia will depend on the places you intend to visit. While autumn and spring are generally the best times for sightseeing or enjoying some of the festivals South Australia is famous for, the outback is great in winter and Kangaroo Valley and the Eyre Peninsula are perfect for a summer getaway.

Weather in South Australia

Like most of Australia, most people find the weather in best in Spring and Autumn best for exploring.

  • Summers can be scorching, particularly away from the coast, and this is not the best time to head to places like Wilpena Pound. However, it is an excellent time to visit the Eyre Peninsula.
  • Winters are mild, but rainfall can be substantial. It can be a good time to road trip away from the coast.
  • Spring edges out the other seasons as our favourite because of the wildflower season and comfortable temperatures. This is also a wonderful time of year to explore Kangaroo Island.
  • Autumn is a popular time to visit Adelaide with major events like the Adelaide Fringe Festival, providing epic entertainment. It’s also the perfect time to explore South Australia’s wine regions.
