Storm Risk Analysis
Kewdale, 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 Kewdale.
Severe thunderstorms affecting Kewdale 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 Kewdale property owners, this reinforces the value of storm-resistant building features and comprehensive insurance.
ClimateNest provides address-level storm risk reports for Kewdale including wind zone classification, hail risk probability, and property-specific mitigation recommendations based on your building characteristics.
Kewdale sits within ClimateNest's suburb-level hazard model for severe storm risk. 2.6% of the suburb's land area is mapped in high-risk severe storm zones and 68.2% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Kewdale.
Kewdale (postcode 6105) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (15.9% of land in high-risk zones), surface flood (12.5% of land in high-risk zones), riverine flood (7% of land in high-risk zones). Exposure is not uniform across Kewdale — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Kewdale prone to hailstorms?
Hail risk in Kewdale depends on the frequency of severe thunderstorm activity in the Western Australia region. BOM tracks severe storm events including hail. Property-specific risk depends on roof design, building orientation, and local storm patterns.
What wind rating applies to buildings in Kewdale?
Under AS/NZS 1170.2, properties in Kewdale are assigned a wind region classification. This rating determines structural design requirements for new buildings. Check with ClimateNest or a structural engineer for your property's classification.
Does storm risk affect insurance premiums in Kewdale?
Yes, storm damage — including wind, hail, and rain ingress — is one of the most common insurance claims in Australia. Properties in higher wind zones or with greater hail exposure may face higher premiums or specific policy conditions.
What storm mitigation measures should Kewdale property owners consider?
Storm mitigation includes impact-resistant roofing, cyclone-rated fixings where required, window and door shutters, regular roof and gutter maintenance, securing outdoor items, and ensuring compliance with current wind load standards under the National Construction Code.
What share of Kewdale is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 15.9% of Kewdale in high-risk zones for bushfire, with a further 64.8% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
