Welcome to Scorcher
On Scorcher, we define heatwaves based on peer-reviewed and published scientific research, conducted at the ARC Centre of Excellence for Climate System Science.
A heatwave is defined as at least three consecutive days where the daily maximum temperature is in the top 10 percent of warmest temperatures for that calendar date.
The website uses daily temperature records that extend back to 1910. See the FAQ page for more details.
If parts of Australia are shaded on the map, the latest data indicate that a heatwave has recently occurred, up until 2 days ago.

Red shading indicates a heatwave of at least 3 days.
