Temperatures across parts of Australia are forecast to run up to 15°C above average over the weekend, according to weather outlooks reported by The West Australian and PerthNow. The reports say some locations are expected to experience unusually warm conditions, with record-setting or near-record temperatures for the month in question.

Both outlets cite the same general expectation that two cities could record their hottest September day in about three years, while another set of locations may see conditions at a comparable level of unusual warmth. PerthNow adds similar framing, describing the likelihood that one in six places will experience these above-average temperatures. The two reports do not present differing explanations for the cause, focusing instead on the magnitude of the forecast and the proportion of areas affected.

Overall, the outlets agree on the key figures: weekend temperatures can reach up to 15°C above average, with a small number of cities potentially seeing their warmest September day for roughly three years.
