The fire danger season has been brought forward for Adelaide Hills and the metropolitan area after temperatures soared across South Australia on Thursday.
The Country Fire Service said the fire season would be brought forward two weeks and start on November 17 because of a drier than average winter across the area and increased temperatures through spring.
It came as the temperature climbed to 33C in Adelaide and close to 40C in some regional centres.
The hot blasted prompted authorities to declare severe conditions in three SA district, the mid-north, the Mount Lofty Ranges and the Riverland.
CFS acting chief officer Andrew Stark said recent breakouts from burn-offs in the Adelaide Hills had also confirmed the need to bring the season forward.
There were five such incidents on Thursday, with fires spreading to nearby grass.
After Thursday's hot weather, a cool change was expected to move across SA early on Friday with Adelaide forecast to have a top temperature of 27C.
