澳大利亚橄榄球队（Wallabies）已抵达日本大阪，准备参加周六与日本队的国际测试赛，但球队需在极端天气条件下进行备战。[1]日本目前正经历第三周的热浪，大阪气温达37度、湿度68%，体感温度接近45度。[1]日本气象厅首次用"极度酷热日"（kokushobi）这一术语记录温度超过40度的天气。[1]
面对这样的条件，Wallabies队已对训练计划做出调整，包括缩短训练时间、增加水分补给和采取降温措施。[1]根据世界橄榄球联合会的热应力指数政策，当热应力指数小于100时为可接受水平，100至250范围内需增加冷却措施，超过250则可延期或暂停比赛。[1]根据现有条件评估，比赛暂未面临延期或取消风险。[1]周六夜间大阪气温预报为28度，并有降雨预报。[1]
队员对条件适应情况表示乐观。钩锋Josh Nasser说："显然这里很热，但我在布里斯班长大。湿度高，温度高，但这与我们在家乡的条件没有区别。"[1]新防线教练Scott McLeod表示："我们已经做了很多工作，这使我们能够聪明地安排这周的训练时间。"[1]
The Australian rugby team arrived in Osaka to prepare for a Saturday match against Japan amid a severe heat wave affecting the country.[1] Osaka has experienced temperatures reaching 37 degrees Celsius with 68 percent humidity, creating a heat index approaching 45 degrees.[1] Japan is in its third week of extreme heat, with the Japan Meteorological Agency recording temperatures exceeding 40 degrees for the first time under the official classification of "kokushobi," or cruelly hot day.[1]
The Wallabies have implemented modified training protocols to address the dangerous conditions, including shortened practice sessions, increased hydration breaks, and cooling measures.[1] According to World Rugby's heat stress index policy, the match does not currently face postponement or cancellation. The policy designates a heat stress index below 100 as acceptable; between 100 and 250, additional cooling measures are required; and above 250, postponement or suspension is permitted.[1] Saturday evening in Osaka is forecast to bring cooler conditions at 28 degrees with expected rainfall.[1]
Wallabies hooker Josh Nasser acknowledged the intensity of the weather while expressing confidence in the team's adaptation. "Obviously it is hot here, but I grew up in Brisbane. High humidity, high temperature, but it is no different from the conditions we have at home," he said.[1] Coach Scott McLeod added that the team has undertaken considerable preparation that enables them to schedule this week's training sessions strategically.[1]
