Heatwaves

A heatwave is a period of unusual hot weather that can cause serious health effects. Heatwaves can make existing medical conditions worse and cause heat-related illness, which may be fatal. 

It can also affect community infrastructure such as the power supply, public transport and other services.

Who is most at risk?

Those most at risk during a heatwave are:

  • people aged over 65 years, especially those living alone,
  • people with medical conditions such as diabetes, kidney disease or mental illness,
  • people taking certain medications,
  • people with problematic alcohol or drug use,
  • people with a disability who may not be able to communicate their discomfort or thirst,
  • people who have trouble moving around,
  • people who are overweight or obese,
  • pregnant women, breastfeeding mothers, babies and young children,
  • people who work or are physically active outdoors, and
  • people who live in the upper levels of buildings constructed before 1975.

Coping with the heat

  • Look after yourself and keep in touch with sick or frail friends, neighbours and relatives,
  • Drink plenty of water,
  • Keep yourself cool using wet towels, putting your feet in cool water and taking cool showers,
  • Spend as much time as possible in cool or air-conditioned buildings,
  • Close blinds during the day and open windows when there is a cool breeze,
  • Don’t leave children, adults or animals in parked cars,
  • Stay out of the sun during the hottest part of the day, if you must go out, stay in the shade and take water with you,
  • Wear loose fitting, light-coloured clothing,
  • Eat smaller meals more often and cold meals such as salads,
  • Make sure food that needs refrigeration is stored properly,
  • Avoid strenuous activity, and
  • Watch or listen to news reports that provide more information during a heatwave.

Preparing for hot weather

  • Service your air conditioner before summer,
  • Stock up on food, water and medicines so you don’t need to go out in the heat,
  • Store medicines at the recommended temperature,
  • Install awnings, shade cloth or external blinds on the sides of the house facing the sun, and
  • Know where your closest ‘cool places’ are.

Preparing for power failure

  • The risk of power outage is greater in extreme weather conditions. Make sure you have a plan in case of a blackout, 
  • Plan what you would do if a heatwave caused a blackout or disrupted public transport,
  • Ensure you have a torch, fully charged mobile phone and battery-operated radio,
  • Consider your need for back-up power and don’t rely on power as part of your bushfire preparedness plan, and
  •  Remember power outages can affect phones, radios and water pumps.
