THE Bureau of Meteorology has issued its long-range forecast for the 2025 spring season.
The long-range forecast is updated weekly for the upcoming 3 months.
For the September-November period, rainfall is likely to be above-average for most of the eastern half of Australia.
There is an increased chance of unusually high rainfall across much of eastern and central parts of Australia.
There is an increased risk of flooding during heavy rainfall on the east coast of New South Wales and south-east Queensland following a wetter than usual year in these regions.
Spring can also be the start of severe weather season and a peak time for severe thunderstorms along Australia’s east coast. Coastal lows can also bring storms in early spring, increasing the risk of damaging winds, heavy rainfall and flash flooding.
Spring rainfall may provide relief to large parts of Victoria, South Australia and western Tasmania experiencing prolonged dry conditions. However, sustained rainfall is needed to replenish soil moisture and water storages.
The first significant rains of the northern wet season are likely to be earlier than usual for most of Queensland and the Northern Territory but later than usual in Western Australia.
Australia’s fire agencies advise there is an increased risk of fire this spring across parts of Western Australia, Victoria and South Australia.
The Bureau is hosting a webinar looking at the long-range forecast for spring 2025 on Tuesday, September 2 from 1pm to 2pm AEST.
The webinar will include forecast information about rainfall, temperature, soil moisture, water storages, and streamflow for Australia in the weeks and months ahead. Register HERE.
