This horizontal bar chart shows the ten longest heatwaves recorded in Broken Hill, a remote outback mining town in far-western New South Wales, Australia, between 1957 and 2026. A heatwave is defined here as four or more consecutive days with maximum temperatures of 40 °C or higher. The bars are ranked by length, with longer bars indicating longer heatwaves. Years from 2000 onwards are coloured red, while years prior to 2000 are shown in yellow. The longest heatwave occurred in 2009, lasting 12 consecutive days. Most of the longest heatwaves have occurred since 2000, indicating that prolonged extreme heat events in Broken Hill have become more common in recent decades.
