A Perfect Autumn Sunday: Adelaide Set for Golden Skies and Mild Temps

Adelaide is set to bask in a quintessential autumn day this Sunday, March 22, 2026. As the city settles into the mid-point of the season, residents can look forward to clear blue skies and a gentle, dry warmth that makes it an ideal day for outdoor festivities or a relaxing coastal drive before the working week resumes.

Morning: A Crisp and Clear Start

The day will begin with the refreshing clarity typical of South Australia in late March. Early risers will experience a crisp start with temperatures sitting comfortably around 15°C to 16°C. With light, variable winds and virtually no cloud cover, the morning sun will quickly take the edge off the early chill. It is a perfect morning for a visit to the local farmers' markets or a walk through the Adelaide Botanic Garden, where the autumn colors are beginning to show.

Afternoon: Warmth Peaks with a Coastal Breeze

As we progress into the heart of the day, the temperature is expected to climb steadily to a pleasant maximum of 29°C. The "mostly sunny" forecast remains the headline, though a few wisps of high-altitude cloud may appear. By mid-to-late afternoon, the wind profile will change. A sea breeze from the south-southwest is forecast to pick up, reaching speeds between 15 and 20 km/h. This will offer a refreshing relief to those enjoying the sun at Glenelg or Henley Beach, while keeping the CBD from feeling overly stifling.

Evening: A Smooth Transition to Night

The evening outlook is equally stable as we approach sunset at approximately 7:24 pm. Temperatures will gradually recede into the low 20s and high teens, making for a mild night perfect for alfresco dining. Winds are predicted to turn east-southeast, bringing a stable air mass over the plains. There are no significant rain events on the horizon for the city, with a negligible 5% chance of any moisture reaching the ground.
