Australia's Bureau of Meteorology predicts an unusually warm winter with below-average rainfall across southern and much of the continent [1, 2].
This forecast is significant because the combination of higher temperatures and lower precipitation increases the risk of drought and environmental stress across key agricultural regions. The shift in weather patterns often correlates with higher fire risks and water scarcity in the southern states.
The weather patterns are expected to persist from May to July 2026 [1]. Meteorologists said these conditions are due to the development of El Niño, a climate pattern that typically brings warmer and drier weather to the Australian region [1, 2].
Tom Saunders said, "Conditions are only a fraction of a degree from El Niño levels" [1].
The Bureau of Meteorology continues to monitor sea surface temperatures and atmospheric pressure to refine the outlook. The current trajectory suggests that much of the continent will experience a departure from typical winter cooling and moisture levels [1, 2].
Southern Australia is expected to be most affected by these shifts. The lack of winter rain can lead to depleted reservoirs and impact crop yields for the following season, a recurring challenge for the region during El Niño cycles [1, 2].
“Conditions are only a fraction of a degree from El Niño levels.”
The onset of El Niño typically disrupts the moisture flow to Australia, leading to a higher probability of drought. When combined with an unusually warm winter, the evaporation rate increases, which can exacerbate water shortages and heighten the risk of early-season wildfires before the traditional summer peak.
