Heatwave conditions ranging from low to extreme are expected for the northern WA, much of the NT, and northern QLD between today (Saturday 20th) and Thursday 25th. Troughs are maintaining heat over the interior bringing clear skies and increasing the temperature for the northern parts of Australia.

It is important to remember that heatwaves represent more than a high maximum temperature on a given day. They are a combination of unusually hot maximum and minimum temperatures over three consecutive days in relation to local weather climate.  

Without lower temperatures at night to recover, heatwaves impact the population's health and infrastructure. There are three levels of heatwave: low (most people can cope), severe (challenging for vulnerable populations), and extreme (dangerous for anyone who doesn’t take protective action).  

Knowing there is a high probability of a coming heatwave, it is crucial to prepare yourself. Doctors and local health authorities understand the impact of heat on each communities' health. They can provide advice on how to prepare and cope with heatwave conditions. You can also look at your State/Territory website for information.
