Storm Risk Analysis

South Granville, New South Wales, 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 South Granville.

Severe thunderstorms affecting South Granville can produce damaging wind gusts, large hail, and intense rainfall. The Bureau of Meteorology issues severe weather warnings for New South Wales, 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 South Granville property owners, this reinforces the value of storm-resistant building features and comprehensive insurance.

ClimateNest provides address-level storm risk reports for South Granville including wind zone classification, hail risk probability, and property-specific mitigation recommendations based on your building characteristics.

South Granville sits within ClimateNest's suburb-level hazard model for severe storm risk. 0% of the suburb's land area is mapped in high-risk severe storm zones and 82.5% 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 South Granville.

South Granville (postcode 2142) 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 (13.9% of land in high-risk zones), riverine flood (13% of land in high-risk zones), surface flood (8.8% of land in high-risk zones). Exposure is not uniform across South Granville — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
