Xmas Day temperatures across Australia’s capital cities will range from the low 20s to high 30s Celsius, with heat building inland. In short, expect a hot to very hot day for most, variable with coastal seabreezes and isolated showers.
What is the typical Xmas Day forecast for Australian capitals?
Based on the live forecast above, typical December 25 conditions see Sydney reaching 27–31°C, Melbourne 25–30°C, Brisbane 29–33°C, Adelaide 28–35°C, Perth 28–34°C, and Hobart 19–24°C. The further inland, the hotter it gets, with Alice Springs often topping 38°C. Coastal cities benefit from afternoon seabreezes, though humidity can build in northern capitals.
Will it rain on Xmas Day?
Rainfall is generally isolated across the south-east and tropical north. The live forecast shows a slight chance of showers for Sydney and Brisbane, while Melbourne and Adelaide tend drier. The northern tropics often see a monsoon burst, so the chance of a storm is higher in Darwin and Cairns. Check the live forecast above for your exact location.
