Coast dodges heatwave but will see blue bottles re...

A DYING easterly swell and a shift back to east, north-easterly winds are set to deliver a benign seven days of weather on the Sunshine Coast while further inland Queensland's western towns swelter with a run of 40-44C daytime temperature peaks.

Bureau of Meteorology forecaster Lauren Pattie said a ridge along the coast formed from a Tasman Sea high would keep conditions stable on the Coast and certainly more comfortable than places like Boulia, Roma and Charleville would be.

Birdsville will peak on Thursday and Friday as temperatures hit 46C during a seven-day run where they will fail to fall below 43C.

Ms Pattie said while the high and trough now in place dictating coastal weather would weaken, it would be replaced by another system that would continue the milder trend that has seen holiday makers pack caravan parks and other accommodation for the past five weeks.

The easterly swell is trending downward from a metre and losing power as the period shortened which combined with the east, north-easterlies will make for less than ideal conditions for surfers.

Power more than perfection has been the tale of the Christmas-New Year surf conditions. With that also diminishing and east, north-easterly winds setting in, the Sunshine Coast is likely to see a return of blue bottles that have harassed swimmers since early December.

Expect today to hit a temperature peak of 31C on a day where light easterlies at dawn swung south west and then east at 15-20km/h on a mostly-sunny day.

Wednesday will also be mostly sunny with light winds early picking up to 15-25km/h from the east, north-east before fading in the evening following what will be another 31C day.

Maximum temperatures will drop slightly to 30C on Thursday on a partly-cloudy day with the slight chance of a shower and light winds early becoming east, north-easterly at 15-20km/h in the morning before fading in the late afternoon.

Friday will also hit 30C on another partly-cloudy day with the slight chance of a shower and winds increasing from light to 15-20km/h from the east, north-east.

Temperatures will increase to daytime peaks of 31C on Saturday and Sunday, both partly-cloudy days with little wind.

Mr Pattie said there was a slight chance of a shower Sunday but that was unlikely in most places.

A partly-cloudy Monday will come with a medium chance of rain as winds that would be light early, swung back to the east, south-east at 15-20km/h.
