South Australia has a Mediterranean climate with mild winters and warm, dry summers – making it the perfect year-round holiday destination!

South Australia’s summer runs from December to February. The average temperature is 28.3 degrees°C but often soars above 30°C. Coastal towns are popular during summer when people flock to the beaches. Winter temperatures range from 8°C to 15°C.

Best Times to Visit South Australia

Spring and Autumn are popular times to visit South Australia. There is usually plenty of sunshine and temperatures hover in the low to mid 20s. Spring is awash with colour and can be lovely and warm. Flowers bloom and the wildlife flourishes.

If you love the sun and heat, South Australian summers can reach well into the high 30’s – especially up in the Outback. Be sure to take hats, sunblock and plenty of water with you on your daily excursions. Winter temperatures are similar to regional New Zealand but as the driest State in Australia, cold, wet rainy winter days are rare. Winter is often a lovely time to visit the cellar doors enjoying a robust shiraz infront of a roaring fire.

Be Sun Smart

Northern parts of the state, such as the Flinders Ranges and the Outback, experience very hot conditions during summer (December – February). Many of these areas are desert so the hot days are followed by very cold nights. Pack a jacket or something warm for the evenings if you are heading into the Outback.

The sun can be extremely intense in Australia, particularly between the hours of 11am and 3pm – we recommend that you wear a wide brimmed hat. Use a maximum protection, broad based spectrum sun screen of at least SPF 30+ and drink plenty of water.
