The Bureau of Meteorology has issued the long-range forecast for the 2025 summer season, and it shows summer days and nights are likely to be warmer than average across most of Australia.
Nationally, summer rainfall is likely to be below average for parts of the west and inland parts of the east.
However, for much of the east coast and south the summer forecast does not currently show a clear rainfall signal: there are near-equal chances of above or below average rainfall.
The forecast will evolve over summer, and the seasonal forecast will be updated every week.
