Is Horsham, VIC Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Horsham faces a moderate risk of flooding due to its proximity to the Wimmera River and other waterways. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- Horsham has a relatively low bushfire risk compared to other parts of Victoria, but is still susceptible due to surrounding grasslands and bushland. Drier conditions and higher temperatures could increase the risk of bushfires.
- Heat
- Horsham experiences hot summers and is vulnerable to heatwaves. Climate change is projected to increase the frequency, intensity, and duration of heatwaves, posing a significant risk to vulnerable populations.
- Storm
- Moderate storm risk — severe thunderstorms with hail and damaging winds
- Postcode
- 3400
- Highest high-risk exposure
- 24.3% of land (bushfire)
Climate Safety Analysis
Horsham in Victoria 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 Horsham'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 Horsham 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.
