We define a heatwave as three or more days of unusually high maximum and minimum temperatures.

Heatwaves have caused more deaths in Australia than any other natural hazard.

Heatwaves have always been a part of life in Australia. Global warming resulting in rising temperatures means extreme weather circumstances are likely to become more intense and frequent.

Heatwaves affect our:

  • health and wellbeing
  • energy and infrastructure
  • public transport
  • agriculture.

Heat can affect anyone. The elderly, babies, young children and outdoor workers are those at risk during a heatwave.
