Summer runs from December to February and is considered peak season, with warm, dry days around 17°C to 29°C (63°F to 84°F). Long daylight hours suit beach visits, outdoor dining, and evening events along the coast and in the city s parklands.
Autumn, from March to May, is a shoulder season with mild temperatures of about 13°C to 23°C (55°F to 73°F). Vineyards in nearby regions turn gold and red, making this a pleasant time for wine tours, city walks, and cultural festivals without the height of summer heat.
Winter spans June to August and is a low season, bringing cooler, wetter days around 8°C to 16°C (46°F to 61°F). It is a comfortable time for museum visits, cosy dining, and exploring the Adelaide Hills, with fewer crowds and a calmer pace in the city.
Spring, from September to November, returns to shoulder season, with fresh greenery and temperatures around 11°C to 22°C (52°F to 72°F). Blossoms in the Botanic Garden and comfortable conditions make it ideal for outdoor activities, city cycling, and trips to nearby coastal or wine regions.
