Is Grange, SA Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Grange faces a moderate risk of flooding due to its low-lying coastal location and proximity to the Patawalonga River. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity.
- Bushfire
- Bushfire risk in Grange is relatively low due to its coastal location and limited vegetation. However, dry vegetation in nearby reserves could pose a threat during extreme heat and wind conditions.
- Heat
- Grange experiences a high risk of heatwaves, particularly during summer. The urban environment and coastal humidity can exacerbate heat stress for vulnerable populations.
- Storm
- Moderate storm risk — occasional severe thunderstorms
- Postcode
- 5022
- Highest high-risk exposure
- 12.8% of land (bushfire)
Climate Safety Analysis
Grange in South Australia has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Grange's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Grange is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Grange including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Grange (postcode 5022) 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 (12.8% of land in high-risk zones), surface flood (9.7% of land in high-risk zones), riverine flood (2.2% of land in high-risk zones). Exposure is not uniform across Grange — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Which climate hazard poses the biggest risk in Grange?
The dominant hazard for Grange depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Grange compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across South Australia suburbs.
Should I be concerned about buying property in Grange?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Grange?
Key projections for South Australia from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Grange.
What share of Grange is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 12.8% of Grange in high-risk zones for bushfire, with a further 59.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
