Storm Risk Analysis
Kojonup, 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 Kojonup.
Severe thunderstorms affecting Kojonup 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 Kojonup property owners, this reinforces the value of storm-resistant building features and comprehensive insurance.
ClimateNest provides address-level storm risk reports for Kojonup including wind zone classification, hail risk probability, and property-specific mitigation recommendations based on your building characteristics.
Kojonup sits within ClimateNest's suburb-level hazard model for severe storm risk. 4.2% of the suburb's land area is mapped in high-risk severe storm zones and 87.9% 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 Kojonup.
Kojonup (postcode 6395) 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 surface flood (8.9% of land in high-risk zones), bushfire (7.6% of land in high-risk zones), riverine flood (5.8% of land in high-risk zones). Exposure is not uniform across Kojonup — 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 Kojonup prone to hailstorms?
Hail risk in Kojonup 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 Kojonup?
Under AS/NZS 1170.2, properties in Kojonup 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 Kojonup?
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 Kojonup 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 Kojonup is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 8.9% of Kojonup in high-risk zones for surface flood, with a further 70.9% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
