- Medium
- 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.
- 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.
- 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.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6076
- Highest high-risk exposure
- 8.5% of land (riverine flood)
Climate Safety Analysis
Lesmurdie in Western Australia has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Lesmurdie's climate safety include heat, bushfire. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Lesmurdie is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Lesmurdie including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Lesmurdie (postcode 6076) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are riverine flood (8.5% of land in high-risk zones), surface flood (6.8% of land in high-risk zones), bushfire (6.1% of land in high-risk zones). Exposure is not uniform across Lesmurdie — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Which climate hazard poses the biggest risk in Lesmurdie?
The dominant hazard for Lesmurdie depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Lesmurdie compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across Western Australia suburbs.
Should I be concerned about buying property in Lesmurdie?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Lesmurdie?
Key projections for Western Australia from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Lesmurdie.
What share of Lesmurdie is exposed to high riverine flood risk?
ClimateNest's hazard overlay maps 8.5% of Lesmurdie in high-risk zones for riverine flood, with a further 82.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
