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 Lesmurdie
Flood
Lesmurdie faces a moderate risk of flooding, primarily from heavy rainfall events and local creek overflows. The risk is influenced by the hilly terrain and existing drainage infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Lesmurdie has a high bushfire risk due to its proximity to extensive bushland areas. Dry summers and strong winds exacerbate the potential for fire spread.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Lesmurdie experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat days projected. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Lesmurdie has a low risk from coastal hazards due to its inland location. Sea level rise and coastal erosion are not significant concerns for this suburb.
Key drivers:
- ·Distance from the coast

Detailed Hazard Analysis
heat Risk
Lesmurdie experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat days projected. This poses a risk to vulnerable populations.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Lesmurdie faces a moderate risk of flooding, primarily from heavy rainfall events and local creek overflows. The risk is influenced by the hilly terrain and existing drainage infrastructure.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development
- ·Inadequate drainage capacity
coastal Risk
Lesmurdie has a low risk from coastal hazards due to its inland location. Sea level rise and coastal erosion are not significant concerns for this suburb.
Primary Drivers
- ·Distance from the coast
bushfire Risk
Lesmurdie has a high bushfire risk due to its proximity to extensive bushland areas. Dry summers and strong winds exacerbate the potential for fire spread.
Primary Drivers
- ·Dry vegetation
- ·High temperatures
- ·Strong winds
- ·Increased ignition sources
What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the elevated bushfire risk.
Price Impact
Properties in high-risk areas may experience a decrease in value.
Buyer Checklist
- 1.Check bushfire risk assessment reports.
- 2.Assess flood risk for the specific property.
- 3.Review insurance coverage and premiums.
- 4.Consider the cost of implementing adaptation measures.
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 Lesmurdie's Climate Risk Profile
Lesmurdie, located in the foothills of the Darling Scarp, is particularly vulnerable to bushfires due to its proximity to dense bushland. The dry summers and strong easterly winds create ideal conditions for fire spread, posing a significant threat to properties and residents.
Flooding is also a concern in Lesmurdie, especially during periods of heavy rainfall. Creeks and drainage systems can become overwhelmed, leading to localized flooding of properties and roads. Climate change is projected to increase the intensity of rainfall events, further exacerbating the risk of flooding.
Heatwaves are becoming more frequent and intense in Lesmurdie, posing a health risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect can also contribute to higher temperatures in built-up areas.
While Lesmurdie is not directly exposed to coastal hazards, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, could still affect the suburb. Residents should take proactive steps to adapt to these changing conditions and mitigate the risks.
