Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Palmyra faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The Swan River is nearby, which could contribute to flooding during extreme weather.
- Bushfire
- The bushfire risk in Palmyra is relatively low due to its urban location. However, proximity to parks and reserves means there's still a potential risk, especially during dry periods.
- Heat
- Palmyra is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — winter storms and occasional severe thunderstorms
- Postcode
- 6157
- Highest high-risk exposure
- 13.2% of land (surface flood)
Climate Safety Analysis
Palmyra 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 Palmyra's climate safety include heat, coastal. 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 Palmyra 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 Palmyra including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Palmyra (postcode 6157) 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 surface flood (13.2% of land in high-risk zones), bushfire (7.6% of land in high-risk zones), riverine flood (5.3% of land in high-risk zones). Exposure is not uniform across Palmyra — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Palmyra safe from climate change?
No location in Australia is entirely immune to climate change impacts. Palmyra has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Palmyra?
The dominant hazard for Palmyra 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 Palmyra 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 Palmyra?
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 Palmyra?
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 Palmyra.
What share of Palmyra is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 13.2% of Palmyra in high-risk zones for surface flood, with a further 79.9% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
