Penrith is expected to face a top of 35° today, with maximums above 40° forecast until Sunday.

However, there is some relief with a sea breeze to keep temperatures about 10-degrees cooler on the coast.

The Weather Bureau’s Sarah Fitton tells John Stanley “severe heatwave conditions” will be widespread.

“We’ve got a lot of heat sitting in the middle of the country which hasn’t really budged so far this summer.”

“Even some extreme heatwave conditions mostly through eastern parts of New South Wales later this week.”
