Is Marchmont, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Flooding can occur from heavy rainfall events, impacting properties near waterways and low-lying areas.
- Bushfire
- Bushfire risk is present due to proximity to bushland areas. Hot, dry conditions can increase the likelihood of fire.
- Heat
- Rising average temperatures and more frequent heatwaves pose a risk to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2582
- Highest high-risk exposure
- 13.5% of land (bushfire)
Climate Safety Analysis
Marchmont in New South Wales 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 Marchmont's climate safety include heat, flood. 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 Marchmont 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.
