El Niño can favour drier conditions in parts of Australia, but it does not switch off rain. The Bureau of Meteorology says Australia’s rainfall depends on several interacting climate influences, so a strong Pacific event does not automatically produce equally strong effects everywhere.
In its September explanation of the current El Niño, the Bureau notes that unusually warm surrounding oceans can supply moisture and energy to rain systems. Indian Ocean conditions, seasonal changes and individual weather systems can strengthen or outweigh the Pacific influence. During winter, north-west cloudbands and cold fronts drew on tropical moisture, helping bring rain to parts of the interior.
That is why a wet spell and El Niño can occur together. National averages also hide regional differences: rain in one area does not mean every district has received enough. For the months ahead, the Bureau recommends checking its regularly updated long-range forecasts, which account for multiple climate drivers rather than relying on the El Niño label alone.
