Melbourne’s weather is famously unpredictable, so check the local forecast each morning and pack layers – a cool start can turn into a warm afternoon, with possible showers arriving quickly.
What is Melbourne’s climate like?
Melbourne has a temperate oceanic climate, meaning mild, changeable conditions year‑round with no extreme heat or cold.
- Summer (Dec–Feb): average maximum 25.3°C, with occasional heatwaves and cool sea breezes.
- Winter (Jun–Aug): average minimum 6.4°C, often overcast with periods of steady rain.
- Spring and autumn are transitional, bringing abrupt temperature shifts and the “four seasons in one day” reputation.
- Rainfall is spread fairly evenly through the year, averaging 649 mm annually.
What should I know about Melbourne’s weather patterns?
The city sits on Port Phillip Bay, and its position near the Southern Ocean drives rapid weather changes.
- A strong afternoon sea breeze often cools the coast after a warm morning.
- Cold fronts from the Southern Ocean can cause sudden drops in temperature and gusty winds.
- Thunderstorms are most common in spring and early summer, usually in the late afternoon.
Does it rain a lot in Melbourne?
Not as much as you might think. Melbourne averages about 140 rain days per year, but total rainfall is moderate – around 650 mm. Many days have only light drizzle, and downpours are usually brief.
When is the best time to visit Melbourne for fine weather?
January and February are the warmest months with the most sunshine. However, March to May and September to November offer pleasant temperatures and fewer crowds, though you should still expect sudden changes.
Why is Melbourne’s weather so unpredictable?
Melbourne sits at the edge of the Southern Ocean where cold fronts interact with warmer inland air. The Bay also creates local sea‑breezes, so conditions can flip from sunny to stormy within an hour – hence the classic “four seasons in one day” tag.
