Adelaide Weather Guide

The driest of Australia’s capital cities, Adelaide has mild, wet winters and hot, dry summers. The city gets the occasional heatwave, but it’s highly unlikely you’ll visit during one of the 3 days a year when the temperature rises to 40 degrees Celsius – generally the average maximum is around 29 degrees. Much of the weather in Adelaide is dependent upon the wind direction, with hot and dry winds from the north and cooler, more humid winds from the south.

Season and Clothing

Summer: December to February

The summer months are hot with plenty of sunny weather, perfect for exploring the outdoors then nestling into an air-conditioned pub with a cold drink. Rainfall is light and infrequent throughout summer. At the end of summer, the Adelaide Festival kicks off with a feast of international theatre, music, dance and visual arts over 2 weeks in cahoots with the 4-week Adelaide Fringe Festival, which takes over the city’s parks, laneways, galleries, cafes and hotels with pop-up performances from cabaret to rapping and salsa dancing to acrobatics. A warm day can quickly turn into a chilly evening, so take a light coat when you head out.

Average temperatures: 17 – 28 degrees Celsius.
Appropriate clothing: Shorts and t-shirts, skirts, swimwear and dresses.
Don’t forget: A light coat for night, sunnies and sunscreen for the day.

Autumn: March to May

Autumn is a great time to visit Adelaide. There’s loads of sunshine about and the temperature rarely reaches beyond the mid-20s. In March, Adelaide celebrates WOMADelaide – a 4-day festival showcasing music, dance and visual arts with amazing food and grassroots shopping on offer too. Autumn is the best time to visit the Barossa Valley when the grape harvest and Barossa Vintage Festival takes place. Don’t miss the Adelaide Food and Wine Festival for a smorgasbord of South Australian goodness either.

Average temperatures: 13 – 24 degrees Celsius.
Appropriate clothing: Jeans and t-shirts, shorts and dresses for warmer days.
Don’t forget: A light jacket for cooler weather, sunglasses, dancing shoes.

Winter: June to August

Adelaide experiences most of its rainfall during these months. Without having a distinct winter, Adelaide is fortunate to have more of a prolonged autumn over 6 months. In July, the city tunes up and salutes the magical axe with the International Guitar Festival.

Average temperatures: 8 – 16 degrees Celsius.
Appropriate clothing: Jeans, long-sleeved shirts, warm clothes for layering.
Don’t forget: A jacket, raincoat and umbrella.

Spring: September to November

Spring is the season for colour in Adelaide as the flowers bloom and the fruit and vegetables go berserk – expect to see, taste and smell an increased variety of local produce at the Adelaide Central Market. The Royal Adelaide Show each September guarantees a hoot with carnival rides and animal shows, and then fashion comes to town in October with Adelaide Fashion Festival.

Average temperatures: 12 – 22 degrees Celsius.
Appropriate clothing: Jeans and t-shirts, shorts and dresses for warmer days.
Don’t forget: A light jacket for cooler weather, sunnies and swimwear for warm days.
