The Bureau of Meteorology issues heatwave warnings before and during severe and extreme heatwaves in Victoria. Find out more about the Bureau’s heatwave warning system

National heatwave warning system 

The Bureau of Meteorology issues heatwave warnings when 10 per cent or more of a weather district is in a severe or extreme heatwave.  

It is based on 3 days of unusually high maximum and minimum temperatures for that location.  

They use 3 heatwave categories based on intensity:

  • low-intensity
  • severe
  • extreme.   

According to the Bureau during these events, the following risks apply.

  • Low-intensity heatwaves - Most people can cope 
  • Severe heatwaves - Vulnerable people at risk
  • Extreme heatwaves - everyone is  at risk, even people who are healthy

Heat warnings are available on the Bureau of Meteorology website, the Bureau of Meteorology app, and their telephone service (1300 978 022).    

More information on these categories and how the Bureau calculates the heatwave forecast is available via the Bureau of Meteorology website.

Heat health warning

We use the Bureau's severe and extreme heatwave warnings and will issue a heat health warning (formerly a heat health alert).

A heat health warning notifies the community, local governments, hospitals, health and community services of the risk and likely impact on people's health.  

The Chief Health Officer may also issue a heat health warning when they consider forecast temperatures pose a health risk for example a single day of extremely high temperatures.
