Sunbury, Victoria, enjoys a temperate climate with warm summers and cool, crisp winters. The live forecast above shows the current conditions, but for planning a visit, the best months are typically November through March for reliable warmth and sunshine, while winter (June–August) brings chilly mornings perfect for a cosy escape.
What is the weather like in Sunbury throughout the year?
Sunbury sits about 40 kilometres north-west of Melbourne’s centre, so it shares the city’s variable weather but tends to be a few degrees cooler, especially overnight. Summer (December–February) averages highs around 26–28°C, with occasional hot spells above 38°C. Autumn and spring are mild, with daytime temperatures between 15–22°C. Winter (June–August) sees maximums of 12–14°C, with frequent frosty mornings and light rainfall. Pack layers year-round; a warm jacket is essential from May to September.
When should I travel to Sunbury for the best weather?
For outdoor activities, aim for late spring (October–November) or early autumn (March–April). These months offer pleasant temperatures, lower humidity, and fewer school-holiday crowds than the peak summer period. If you’re after a winter escape, July is the coolest month, ideal for cosy winery visits—just bring a coat for those frosty starts.
Does Sunbury get snow?
Snow is extremely rare in Sunbury due to its low elevation (approx. 220 metres). Frost and fog are common in winter, but any snow would be a light dusting, typically occurring once every few decades.
How does Sunbury weather compare to Melbourne?
Sunbury is usually 2–4°C cooler than Melbourne’s city centre, especially overnight. It also receives slightly less rainfall overall, but the same changeable patterns apply—expect four seasons in one day, particularly in spring and autumn.
Is Sunbury windy?
Sunbury can be breezy, especially in spring and summer when northerly winds bring hot spells. Afternoon sea breezes from Port Phillip Bay often arrive later in the day, offering relief on hot afternoons. Check the severe weather warning page for strong wind alerts.
