Storm Risk Analysis

Augusta-Margaret River, Western Australia, has a moderate storm risk profile. This includes exposure to severe thunderstorms, hail, damaging winds, and — in tropical regions — cyclone impacts. The applicable wind region classification under AS/NZS 1170.2 influences building design standards for Augusta-Margaret River.

Severe thunderstorms affecting Augusta-Margaret River can produce damaging wind gusts, large hail, and intense rainfall. The Bureau of Meteorology issues severe weather warnings for Western Australia, and historical storm data helps characterise the frequency and intensity of events in the region.

CSIRO research indicates that the intensity of severe convective storms — including those producing hail and damaging winds — may increase in a warming climate. For Augusta-Margaret River property owners, this reinforces the value of storm-resistant building features and comprehensive insurance.
