Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Grange
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.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
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.
Key drivers:
- ·Dry vegetation
- ·Extreme heat
Heat
Grange experiences a high risk of heatwaves, particularly during summer. The urban environment and coastal humidity can exacerbate heat stress for vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Grange is exposed to coastal hazards such as sea level rise and coastal erosion. Low-lying areas are vulnerable to inundation during storm surges and high tides.
Key drivers:
- ·Sea level rise
- ·Storm surge

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Grange's Climate Risk Profile
Grange, a suburb of Adelaide, South Australia, is increasingly vulnerable to the impacts of climate change. Its coastal location makes it particularly susceptible to sea level rise, storm surges, and coastal erosion. The low-lying topography exacerbates the risk of flooding from intense rainfall events and rising sea levels.
Heatwaves are becoming more frequent and intense, posing a significant threat to public health, especially for elderly and vulnerable populations. The urban environment of Grange contributes to the urban heat island effect, further amplifying heat stress during summer months.
While bushfire risk is relatively low compared to other regions, dry vegetation in nearby reserves could still pose a threat during extreme heat and wind conditions. It is important to maintain vegetation and implement fire safety measures.
The local council and state government are working to address these challenges through adaptation strategies and infrastructure improvements. However, individual preparedness and community resilience are crucial for mitigating the impacts of climate change in Grange.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
