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 Mandurah
Flood
Mandurah faces a moderate risk of flooding due to its low-lying coastal location and proximity to the Peel-Harvey Estuary. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity, causing inundation of low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk in Mandurah is moderate, with areas of bushland surrounding residential zones. Hot, dry summers and strong winds can create conditions conducive to bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Mandurah experiences a high risk of heatwaves, particularly during the summer months. Increasing average temperatures and more frequent extreme heat events pose a threat to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Coastal erosion and inundation are moderate risks for Mandurah, given its extensive coastline and low-lying areas. Sea level rise and storm surges can exacerbate these risks.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in areas at high risk of flooding, bushfires, and coastal erosion.
Price Impact
Properties in areas at high risk of climate-related hazards may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and bushfire prone area maps.
- 2.Assess the property's vulnerability to coastal erosion and inundation.
- 3.Inquire about the property's insurance history and potential premium increases.
- 4.Consider the property's energy efficiency and potential for renewable energy generation.
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 Mandurah's Climate Risk Profile
Mandurah, a coastal city in Western Australia, is vulnerable to a range of climate-related hazards. Its low-lying geography and proximity to the coast make it susceptible to flooding and coastal erosion. Rising sea levels and more intense storm surges are expected to increase the frequency and severity of coastal inundation events.
Bushfire risk is also a concern, particularly in areas bordering bushland. Hot, dry summers and strong winds create conditions conducive to bushfires, which can threaten lives and property. Residents should be aware of bushfire safety measures and have a plan in place in case of an emergency.
Heatwaves are becoming more frequent and intense in Mandurah, posing a significant health risk to vulnerable populations, such as the elderly and those with chronic illnesses. It is important to stay hydrated, seek shelter in air-conditioned environments, and avoid strenuous activity during heatwaves.
The City of Mandurah is taking steps to address climate change and mitigate its impacts. These include investing in flood mitigation infrastructure, implementing bushfire management strategies, and promoting energy efficiency and renewable energy. However, further action is needed to protect the community from the growing risks of climate change.

How will climate change affect property values in Mandurah?
Properties in areas at high risk of climate-related hazards, such as flooding and coastal erosion, may experience a decrease in value. Insurance premiums are also likely to increase in these areas. It is important to consider these risks when buying or selling property in Mandurah.
What is the urban heat island effect and how does it affect Mandurah?
The urban heat island effect is when urban areas experience higher temperatures than surrounding rural areas due to human activities and infrastructure. In Mandurah, this can exacerbate the impact of heatwaves, making it even hotter in built-up areas. Planting trees and using reflective building materials can help mitigate this effect.
