Double digit rainfall totals and thunderstorms have been forecast for parts of the Sunshine Coast later this week, according to the weather bureau.

The bureau has forecast Monday and Tuesday to be relatively "benign" thanks to a high pressure ridge but forecaster Kimba Wong said it would likely change from Wednesday to Friday.

Ms Wong said the change was due to a combination of an inland surface trough that's currently unstable and a series of upper troughs moving north.

"The inland trough is slowly moving east and it's quite moist and unstable, then we also have a series of upper troughs," Ms Wong said.

"It depends how amplified they are, but there's plenty of moisture in the atmosphere to trigger storms.

"Mid-range rainfall in double digits which could continue to Friday."

Ms Wong said humidity levels were rising which would likely fire up any storm potential.

Slightly above average temperatures of 29-30C have been forecast for Maroochydore on Monday, up on the March average of 28C.

Overnight temperatures of 20C are expected.

Ms Wong said despite no hazardous surf warnings a large southerly swell remained offshore which would impact any open beaches, particularly north of Noosa Heads.
