Heatwaves or extreme heat events can have serious impacts on people's health.
Heatwaves or extreme heat events are times of abnormally hot weather lasting several days. It is based on the three-day forecast minimum and maximum temperatures, compared to historical temperatures over the last 30 days, for a particular location.
Climate projections show extreme heat events are occurring more often and with greater intensity.
It is important you prepare early, plan for the first heatwave and protect yourself.
