Overview
- Australia’s Bureau of Meteorology lists city forecasts: Sydney partly cloudy with a shower risk, Melbourne cool and cloudy, Brisbane with showers and possible thunderstorms, Darwin storm-prone, and Perth mostly sunny near 39°C.
- Perth is expected to be Australia’s hottest capital at about 39°C with a warm 25°C night, as a west coast trough drives hot north-easterly winds, according to the bureau and meteorologist Jessica Lingard.
- South-east Australia trends cool to mild with mostly dry conditions for Victoria and South Australia, showers for western and southern Tasmania, and broad shower and storm chances in Queensland including the tropical north.
- New Zealand’s MetService signals an unsettled Christmas with the east coast favoured for better conditions, a thunderstorm risk from South Auckland to mid‑Canterbury, and temperatures roughly in the 20s for many centres including Auckland 25°C and Wellington 20°C.
- Context from recent outlooks notes a hotter, drier summer is likely across much of Australia despite a weak La Niña, with elevated heat and fire risk in parts of the country and persistent tropical moisture bringing shower and flood risks in the north.
