These Australian cities experience the most frequent extreme heat events, with many recording over 100 days per year where temperatures exceed 35°C. This threshold defines intense heat stress conditions that pose serious physiological challenges to human comfort and safety. Outback locations like Marble Bar and Carnarvon dominate this list, where extreme heat extends well beyond summer into adjacent seasons. These extreme heat days pose significant health risks, including heat exhaustion, dehydration, and heat-related illness, requiring careful planning for outdoor activities and robust cooling infrastructure. The frequency of 35°C plus days correlates with reduced work productivity, increased electricity demand for cooling, and vulnerability for at-risk populations including elderly residents and outdoor workers.
