Perth’s northern suburbs cop the brunt of the state's wet and wild winter, new RAC data shows.

A breakdown of insurance claims related to storm damage throughout June, July and August this year found Ballajura had taken out the unenviable title of Perth’s "stormiest" suburb during that period.

Residents in Ballajura lodged 174 claims with the insurer throughout winter, followed by Morley at 145 and Dianella with 119.

Six suburbs north of Perth featured on the RAC’s top 10 list, while only four from south of the river made the cut.
