The Bureau has released its 2024 Summer Long-Range Forecast, which shows that summer is likely to be warmer than average across most of the country.
Also, more than usual summer rainfall is likely for many parts of the country, particularly in December.
Most of the country is more likely to have a typical range of January rainfall, although parts of eastern New South Wales and south-east Queensland may see above average rainfall.
October to April is Australia's peak time for severe thunderstorms, tropical cyclones, flooding, heatwaves and bushfires.
Severe thunderstorms are more common in the warmer months, bringing heavy rainfall, damaging winds, large hail and the risk of flooding anywhere in Australia.
The Long-Range Forecast is updated weekly and provides a three-month outlook for rainfall and temperature.
