Perth is set to swelter through a heatwave until at least the middle of next week.
The Weather Bureau is predicting a top of 41 degrees today and tomorrow.
Noel Puzey from the bureau says the hot weather will continue, with the heat wave expected to last a total of nine days.
"The cooler change will start to develop through Wednesday but until then temps are 39 or above, so still a hot spate of weather there," he said.
"It's an unusually long period of hot conditions above 35 but it's not at all unusual for Perth to have a heatwave through the Summer months.
"Normally we'd get a change for a cooler day somewhere in between there so a run of nine days in unusual but it's not a record, the most has been 10."
