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

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

Heatwave summary maps are available for today and tomorrow.

There are six cool tips to help you and your loved ones stay safe and well during a heatwave:

  • Sleep in the coolest part of the house—it might not be your bedroom.
  • Fill a small spray bottle with water—it's a great way to keep cool, especially for children.
  • Add a slice of lemon and ice cubes to your water.
  • Set your air conditioners to the cool setting.
  • Register older family members for the Red Cross Telecross REDi service on 1800 188 071.
  • Make sure pets have cool spots, shade and many bowls of iced water. Bring them inside during the day.

Never leave children or pets alone in a parked car, especially during a heatwave.

Heatwaves are more than just hot weather. When it’s hot during the day and it doesn’t cool down at night, it’s very hard for your body to cool itself down.

Heatwaves also bring risks to your health and wellbeing, and anyone can be affected. Keep an eye on your loved ones who have existing health conditions because they can become ill very quickly during heatwaves.
