Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts

- Flood
- Horsfield Bay faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
- Bushfire
- The risk of bushfires in Horsfield Bay is moderate, given the surrounding bushland. Drier conditions and higher temperatures are expected to increase the frequency and intensity of bushfires.
- Heat
- Horsfield Bay is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2256
- Highest high-risk exposure
- 20.3% of land (bushfire)
Climate Safety Analysis
Horsfield Bay 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 Horsfield Bay'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 Horsfield Bay 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.
