Check the live forecast above for today’s conditions, then plan your day around Adelaide’s classic Mediterranean rhythm – it’s the best way to make the most of a climate that can switch from a hot northerly to a cool sea breeze in hours.
What’s driving Adelaide’s weather today?
The live forecast above reflects the dominant influence of the Gulf St Vincent and the surrounding ranges. A high-pressure system often brings clear skies and light winds, while a trough from the west can draw down hot air from the interior. If you see a south-westerly change forecast, expect temperatures to drop quickly – that’s Adelaide’s signature afternoon sea breeze, especially in summer.
How does the weather vary through the year?
Adelaide enjoys mild, wet winters and hot, dry summers. Winter (June–August) sees most of the annual rainfall, with fronts moving across from the Southern Ocean. Summer (December–February) is dominated by high pressure, but occasional heatwaves push temperatures above 40°C. Spring and autumn are short, transitional seasons with pleasant conditions – ideal for exploring the city’s parks and hills.
Does Adelaide get heatwaves?
Yes, especially in January and February when a northerly airflow from the desert pushes temperatures above 40°C for several days. The sea breeze usually provides relief by late afternoon, but overnight temperatures can stay high.
When is the best time to visit for mild weather?
March–May and September–November offer the most comfortable conditions, with daytime temperatures between 18°C and 25°C and lower humidity. These shoulder seasons also have fewer extreme weather events.
Is Adelaide windy?
Wind is common, particularly in spring and early summer. The afternoon sea breeze can gust to 30–40 km/h along the coast, while winter fronts bring strong north-westerly winds ahead of rain.
