South Australia is a year-round destination and the best time to visit will depend on the places you intend to go. While autumn and spring are generally the best times for sightseeing or enjoying 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. We spent five weeks driving around South Australia in autumn, and this was a perfect all round time to explore this beautiful, underrated state.

The best time to visit South Australia’s Main regions

The best time of year to visit the Barossa Valley and other wine regions? – If you are planning to visit some South Australian wineries, then autumn is harvest time and also when the leaves change colour.

When is the best time of year to visit the Flinders Ranges? The weather cools between April and October, making it perfect for taking a few hikes around Wilpena Pound.

When is the best time of year to visit Kangaroo Valley? Most people enjoy Kangaroo Valley in the summer, when you can swim at the most beautiful beaches and enjoy longer days to explore.

When is the best time of year to visit Adelaide? March and April are great times to visit Adelaide. If your dates coincide with any of the big festivals, sort your accommodation early for the best choice and price. This is particularly true of March when pleasant weather and significant events combine.

Weather in South Australia

With its coastline facing the Southern Ocean and a vast area cover by some of the country’s biggest deserts, the temperature in South Australia can see some extremes.

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

  • Summer 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.
