What is the overall summer weather outlook for Australia?
Summer runs from December to February. The Bureau’s long-range forecast points to warmer-than-average days and nights for nearly all regions. Rainfall is likely to be above median for parts of Queensland, New South Wales, and Victoria, while Western Australia and South Australia may see below-average rain. This pattern is influenced by a weak La Niña-like setup in the Pacific and warmer ocean temperatures around northern Australia.
Which cities will be hottest or wettest?
