澳大利亚布里斯班本周末将经历九月最炎热的开局1。澳大利亚气象局预报周日最高气温达35度，较该月平均气温26度高出9度1。据气象部门高级气象学家费利姆·汉尼菲介绍，九月第一周可能出现连续4天气温超过30度的情况，这将是至少26年来首次，而上一次布里斯班在该时期录得3天超过30度的高温是在2019年1。
尽管气温创下新高，但这波高温可能不符合官方热浪预警标准1。汉尼菲指出，获得热浪预警需要满足两个条件：既要有显著温暖的夜间最高气温，也要有白天最高气温1。由于这个周末夜间气温不会保持高温，因此不会被列为正式热浪事件1。
Brisbane is poised to experience its hottest start to September in the current century this weekend, with temperatures expected to reach 35 degrees Celsius on Sunday 1. This forecast represents a departure of approximately 9 degrees above the typical September average of 26 degrees 1.
The early-month surge may mark an unprecedented occurrence, with meteorologists predicting that the first week of September could see four consecutive days exceeding 30 degrees Celsius—potentially the first time this has happened in at least 26 years 1. The last instance of three days surpassing 30 degrees during Brisbane's first week of September occurred in 2019 1.
Despite the exceptional warmth, authorities have stopped short of issuing a heatwave warning. According to Phelim Hanafin, a senior meteorologist with the Australian Bureau of Meteorology, the threshold for such warnings requires both persistently warm nighttime temperatures and elevated daytime highs 1. In this case, while daytime temperatures will soar, overnight conditions are not expected to remain consistently hot, placing the event outside the technical definition of a heatwave 1.
