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 Noarlunga
Flood
Noarlunga faces a moderate risk of flooding, primarily from the Onkaparinga River and heavy rainfall events. The risk is expected to increase with climate change due to more intense rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·River overflow
Bushfire
The bushfire risk in Noarlunga is relatively low compared to other areas in South Australia, but still present due to nearby vegetation. Hotter, drier conditions are projected to increase this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Noarlunga experiences a high heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses a significant threat to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Noarlunga has a moderate coastal risk due to its proximity to the coast. Sea level rise and coastal erosion are potential threats, particularly to low-lying areas.
Key drivers:
- ·Sea level rise
- ·Coastal erosion

Detailed Hazard Analysis
heat Risk
Noarlunga experiences a high heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses a significant threat to vulnerable populations.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Noarlunga faces a moderate risk of flooding, primarily from the Onkaparinga River and heavy rainfall events. The risk is expected to increase with climate change due to more intense rainfall.
Primary Drivers
- ·Increased rainfall intensity
- ·River overflow
- ·Urban development
coastal Risk
Noarlunga has a moderate coastal risk due to its proximity to the coast. Sea level rise and coastal erosion are potential threats, particularly to low-lying areas.
Primary Drivers
- ·Sea level rise
- ·Coastal erosion
- ·Storm surges
bushfire Risk
The bushfire risk in Noarlunga is relatively low compared to other areas in South Australia, but still present due to nearby vegetation. Hotter, drier conditions are projected to increase this risk.
Primary Drivers
- ·Increased temperatures
- ·Drier conditions
- ·Vegetation density
What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase in areas with higher climate risk.
Price Impact
Properties in high-risk areas may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Consider the potential impact of sea level rise if near the coast.
- 4.Review insurance options and premiums.
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 Noarlunga's Climate Risk Profile
Noarlunga, located in South Australia, is projected to experience increasing climate risks in the coming decades. The primary concerns are rising temperatures, more frequent heatwaves, and increased flooding potential. Sea level rise and coastal erosion also pose a threat, although less severe than heat and flooding.
The risk of flooding is driven by the Onkaparinga River and the potential for intense rainfall events. Climate change is expected to increase the frequency and intensity of these events, leading to higher flood risks for properties near the river and in low-lying areas. Effective flood management strategies are crucial to mitigate these risks.
Heatwaves are becoming more frequent and intense, posing a significant threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. Urban planning and building design should prioritize heat mitigation strategies to reduce the impact of extreme heat.
While the bushfire risk is relatively lower compared to other regions, it is still a concern, particularly in areas adjacent to bushland. Maintaining vegetation and implementing bushfire prevention measures are essential to minimize the risk of bushfires.
Addressing these climate risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improving drainage infrastructure, promoting water conservation, and enhancing community resilience, will be crucial to ensure a sustainable future for Noarlunga.
