Weather In Melbourne Australia

Melbourne’s weather is famously unpredictable, with conditions that can shift from warm sun to cool drizzle and gusty wind within a single afternoon. Located between Port Phillip Bay and the Great Dividing Range, the city experiences rapid changes as competing air masses collide over the region.

Why does Melbourne’s weather change so quickly?

Melbourne sits at a latitude where cool, damp air from the Southern Ocean meets hot, dry air from the continent, creating an almost constant state of flux.

• The city’s position on the boundary of contrasting air masses means the weather in Melbourne Australia today can differ markedly from the morning forecast
• Spring and autumn are the most volatile seasons, with cold fronts sweeping through every few days
• The “cool change” — a sudden southerly wind shift — is a defining summer feature, often dropping temperatures by 10°C or more in an hour
