Health authorities say good planning has resulted in a very low number of heat-related illnesses in the far west.
Fewer than five people were treated at the Far West Local Health District's hospitals for heat-related illnesses, despite temperatures reaching into the mid-40s.
Co-ordinator of environmental health services, Ingo Steppat, says far west residents are generally familiar with hot weather.
He says they know they should plan ahead and drink plenty of water.
"They are used to living out in desert conditions and hot climates and even though we've been fortunate with last year not having a very hot summer, I think it's coming back with a vengeance this year and I think people are remembering the times when it was really, really hot," he said.
Mr Steppat says residents should plan ahead for more hot weather forecast for next week, and try to avoid car trips in the middle of the day.
"We seem to know what we're going to be doing over the next couple of days, so if we still have to do that, if we can't postpone it or anything., just make sure you carry plenty of water and let people know you're on the move," he said.
"And particularly with bushfires around, it's good to keep some sort of wool blanket in the car that you can use to protect yourself from a fire should you get caught up in it."
The Bureau of Meteorology is predicting more hot weather around the far west from tomorrow.
