The weather forecast seems to change from day to day, but the current estimate is 40C for Christmas Day and very hot weather on Christmas Eve.
The Government of South Australia has activated support services for people sleeping rough who need protection from the extreme heat.
Some shelters will extend their operating hours, including keeping their doors open through the night.
Call SA Homelessness Gateway on 1800 003 308.
See SA Health for tips on staying healthy in the heat.
Take care, everyone.
