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 South Perth
Flood
South Perth faces a moderate risk of flooding, primarily from riverine sources and intense rainfall events. The Swan River poses a constant threat, and localized flooding can occur due to inadequate drainage.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in South Perth is relatively low due to its urbanized environment and distance from large bushland areas. However, parks and reserves can still pose a localized risk.
Key drivers:
- ·Proximity to parks and reserves
- ·Dry vegetation in summer
Heat
South Perth experiences a high heat risk, with increasing average temperatures and more frequent heatwave events. Urban heat island effect exacerbates the problem.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
South Perth is exposed to coastal risks due to its proximity to the Swan River and the coast. Sea level rise and storm surges can lead to erosion and inundation.
Key drivers:
- ·Sea level rise
- ·Increased storm surge intensity

Detailed Hazard Analysis
heat Risk
South Perth experiences a high heat risk, with increasing average temperatures and more frequent heatwave events. Urban heat island effect exacerbates the problem.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
South Perth faces a moderate risk of flooding, primarily from riverine sources and intense rainfall events. The Swan River poses a constant threat, and localized flooding can occur due to inadequate drainage.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Urban development reducing permeable surfaces
coastal Risk
South Perth is exposed to coastal risks due to its proximity to the Swan River and the coast. Sea level rise and storm surges can lead to erosion and inundation.
Primary Drivers
- ·Sea level rise
- ·Increased storm surge intensity
- ·Erosion
bushfire Risk
Bushfire risk in South Perth is relatively low due to its urbanized environment and distance from large bushland areas. However, parks and reserves can still pose a localized risk.
Primary Drivers
- ·Proximity to parks and reserves
- ·Dry vegetation in summer
What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase in areas at high risk of flooding or coastal inundation.
Price Impact
Properties in vulnerable locations may experience a decrease in value due to climate risks.
Buyer Checklist
- 1.Check flood maps and coastal inundation zones.
- 2.Assess the property's vulnerability to heatwaves.
- 3.Inquire about insurance costs and coverage.
- 4.Consider the long-term impacts of climate change on property value.
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 South Perth's Climate Risk Profile
South Perth, located on the Swan River, is vulnerable to a range of climate-related risks. The suburb's low-lying areas are susceptible to flooding from both riverine and rainfall sources. Climate change is projected to increase the intensity and frequency of extreme rainfall events, further elevating the flood risk.
Heatwaves are becoming more common and intense in South Perth, posing a significant threat to public health, especially for vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, exacerbates the heat.
Coastal erosion and inundation are also concerns for South Perth, given its proximity to the Swan River and the coast. Sea level rise is expected to worsen these risks, potentially impacting infrastructure and property values.
While bushfire risk is relatively low compared to other areas in Western Australia, parks and reserves within and around South Perth can still pose a localized threat, particularly during dry summer months. Residents should maintain their properties to reduce fuel loads and be aware of bushfire safety guidelines.

What is the City of South Perth doing to address climate change?
The City of South Perth is developing and implementing climate strategies to reduce greenhouse gas emissions and adapt to the impacts of climate change. These strategies include improving drainage infrastructure, increasing tree canopy cover, and promoting sustainable development.
How can I prepare my property for climate change impacts?
You can prepare your property for climate change impacts by checking flood maps and coastal inundation zones, assessing your property's vulnerability to heatwaves, inquiring about insurance costs and coverage, and considering the long-term impacts of climate change on property value.
Where can I find more information about climate change in South Perth?
You can find more information about climate change in South Perth on the City of South Perth website, the Department of Fire and Emergency Services website, and the Bureau of Meteorology website.
What is the urban heat island effect and how does it affect South Perth?
The urban heat island effect is a phenomenon where urban areas experience higher temperatures than surrounding rural areas due to the concentration of buildings and paved surfaces. This effect exacerbates heatwaves in South Perth, making it even hotter.
