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 Subiaco
Flood
Subiaco faces a moderate risk of flooding, primarily from intense rainfall events and potential stormwater runoff. The area's relatively flat terrain and existing drainage infrastructure contribute to this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The risk of bushfire in Subiaco is relatively low due to its urbanized environment and distance from large areas of dense vegetation. However, parks and reserves in and around the suburb could pose a localized risk.
Key drivers:
- ·Proximity to parks and reserves
- ·Dry vegetation
Heat
Subiaco is likely to experience more frequent and intense heatwaves in the future. The urban heat island effect exacerbates this risk, leading to higher temperatures compared to surrounding areas.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Subiaco is located inland and does not face direct coastal inundation risks. However, it may experience indirect impacts from coastal hazards such as sea level rise and storm surges affecting nearby coastal communities and infrastructure.
Key drivers:
- ·Sea level rise
- ·Storm surge

Detailed Hazard Analysis
heat Risk
Subiaco is likely to experience more frequent and intense heatwaves in the future. The urban heat island effect exacerbates this risk, leading to higher temperatures compared to surrounding areas.
Primary Drivers
- ·Climate change
- ·Urban heat island effect
- ·Reduced vegetation cover
flood Risk
Subiaco faces a moderate risk of flooding, primarily from intense rainfall events and potential stormwater runoff. The area's relatively flat terrain and existing drainage infrastructure contribute to this risk.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development
- ·Aging drainage infrastructure
coastal Risk
Subiaco is located inland and does not face direct coastal inundation risks. However, it may experience indirect impacts from coastal hazards such as sea level rise and storm surges affecting nearby coastal communities and infrastructure.
Primary Drivers
- ·Sea level rise
- ·Storm surge
- ·Coastal erosion
bushfire Risk
The risk of bushfire in Subiaco is relatively low due to its urbanized environment and distance from large areas of dense vegetation. However, parks and reserves in and around the suburb could pose a localized risk.
Primary Drivers
- ·Proximity to parks and reserves
- ·Dry vegetation
- ·Wind patterns
What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to climate-related risks.
Price Impact
Properties in areas prone to flooding or heat stress may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to heat stress.
- 3.Consider the potential impacts of climate change on insurance premiums.
- 4.Evaluate the property's energy efficiency.
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 Subiaco's Climate Risk Profile
Subiaco, an inner-western suburb of Perth, is increasingly vulnerable to the impacts of climate change. The most significant risks include rising temperatures, increased frequency of heatwaves, and potential for flooding due to intense rainfall events.
The urban heat island effect is a major concern for Subiaco. Densely built-up areas retain more heat, leading to higher temperatures compared to surrounding areas. This can exacerbate the health impacts of heatwaves, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions.
Flooding is another potential risk for Subiaco. While the suburb is not located directly on a major river, intense rainfall events can overwhelm drainage systems, leading to localized flooding. Climate change is expected to increase the frequency and intensity of these rainfall events, further increasing the risk of flooding.
Although Subiaco is not directly on the coast, it may experience indirect impacts from coastal hazards. Sea level rise and storm surges could affect nearby coastal communities and infrastructure, potentially disrupting transportation and supply chains. It is important for Subiaco to consider these indirect impacts when planning for climate change.
Addressing these climate risks requires a multi-faceted approach. This includes measures to reduce greenhouse gas emissions, adapt to the impacts of climate change, and build community resilience. Residents, businesses, and local government all have a role to play in creating a more climate-resilient Subiaco.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.

Frequently Asked Questions
What are the main climate change risks for Subiaco?
The main climate change risks for Subiaco include increased frequency and intensity of heatwaves, potential for flooding due to intense rainfall events, and indirect impacts from coastal hazards.
How will climate change affect property values in Subiaco?
Properties in areas prone to flooding or heat stress may experience a decrease in value. It is important to assess a property's vulnerability to these risks before purchasing.
What is the urban heat island effect and how does it affect Subiaco?
The urban heat island effect is the phenomenon where urban areas are significantly warmer than surrounding rural areas due to the concentration of buildings, roads, and other infrastructure. This can exacerbate the health impacts of heatwaves in Subiaco.
What can I do to prepare for heatwaves in Subiaco?
To prepare for heatwaves, stay hydrated, seek shade, use air conditioning or fans, and check on vulnerable neighbors and family members.
How is the City of Subiaco addressing climate change?
The City of Subiaco is developing and implementing climate change strategies to reduce greenhouse gas emissions, adapt to the impacts of climate change, and build community resilience. Check the council website for more information.
Where can I find information about flood risks in Subiaco?
Information about flood risks in Subiaco can be found on the City of Subiaco website and the Department of Water and Environmental Regulation website.
