Brisbane is set for temperatures up to 10 degrees above average for the rest of the month, with Monday peaking at 36 degrees.

Kev Hutchins of the Bureau of Metrology said the south-east could thank a warm air mass, which will stick around for most of next week, for the above average temperatures, with the only relief coming on Thursday when the mercury will drop back down to a comparatively cool 28 degrees.

"We have a high in the Tasman Sea and that is directing warm northerly winds over much of eastern and southern Queensland and there is a really weak pressure pattern at the moment across the centre of the continent and there is nothing around it that is really going to change the air mass, or push it away," the metrologist said.

"So this warmer air that is being generated, the sunny skies, warm northerly winds, this warm air mass will continue to circulate around the state and northern New South Wales and the Northern Territory, there is nothing really to sweep it away in the next few days."

Mr Hutchins said a small amount of relief should reach the south-east on Tuesday night.

"We will see a surface trough move through the state reaching us probably on Tuesday – so we will see the wind direction change and the warm air mass will be replaced by one which is a little cooler," he said.

"So basically, that is why it is just very unchanging at the moment. The warm air is just hanging around."

October's average is usually 26 degrees, with November warming up to an average of 28 degrees.

But Mr Hutchins said not to expect any relief at night – Saturday night will be the coolest, at 18 degrees, with temperatures not dropping much below 21 degrees once the sun goes down for the rest of the week.
