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 Allambie Heights
Flood
Allambie Heights faces a moderate risk of flooding, primarily from heavy rainfall events and localised stormwater runoff. Properties in low-lying areas are more vulnerable.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Located near significant bushland, Allambie Heights is exposed to a high risk of bushfires, especially during dry and windy conditions. The risk is exacerbated by increasing temperatures and drier vegetation.
Key drivers:
- ·Climate change
- ·Dry vegetation
Heat
Allambie Heights experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves. Vulnerable populations, such as the elderly and those with chronic illnesses, are particularly at risk.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Allambie Heights has a low coastal risk due to its distance from the immediate coastline. However, it may experience indirect impacts from coastal storms and sea-level rise.
Key drivers:
- ·Sea-level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase in the future due to the rising risk of flooding and bushfires.
Price Impact
Properties in high-risk areas may experience a decrease in value as climate risks become more apparent.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to flooding and bushfires.
- 3.Consider the cost of insurance and potential increases in the future.
- 4.Inquire about council plans for managing climate risks.
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 Allambie Heights's Climate Risk Profile
Allambie Heights, located on the Northern Beaches of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, while heavy rainfall events can lead to localised flooding. Rising temperatures and more frequent heatwaves pose additional challenges for residents.
The primary climate risks for Allambie Heights include flooding, bushfires, and heatwaves. Flooding is mainly caused by intense rainfall and stormwater runoff, particularly in low-lying areas. Bushfires are a significant threat due to the suburb's location near extensive bushland. Heatwaves are becoming more frequent and intense, impacting vulnerable populations.
Climate change projections indicate that these risks will intensify in the coming decades. Increased rainfall intensity is expected to worsen flooding, while drier conditions and higher temperatures will increase the likelihood and severity of bushfires. Heatwaves will become more frequent and prolonged, posing a greater risk to public health.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Mitigation efforts focus on reducing greenhouse gas emissions to slow down climate change. Adaptation measures involve preparing for the impacts of climate change by improving infrastructure, implementing early warning systems, and promoting community awareness.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
