Is Trafalgar South, VIC Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Trafalgar South faces a medium to high risk of flooding, primarily due to its proximity to waterways and low-lying areas. Heavy rainfall events can overwhelm local drainage systems and lead to inundation.
- Bushfire
- The suburb has a moderate bushfire risk, influenced by surrounding rural areas and vegetation. While not directly on the urban fringe of major bushland, ember attack and proximity to grasslands pose a threat.
- Heat
- Trafalgar South is exposed to significant heat stress, with a high number of days exceeding 35°C projected. The urban form and lack of extensive tree canopy in some areas contribute to the urban heat island effect.
- Storm
- Moderate storm risk — severe thunderstorms with hail and damaging winds
- Postcode
- 3824
- Highest high-risk exposure
- 11.9% of land (surface flood)
Climate Safety Analysis
Trafalgar South 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 Trafalgar South'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 Trafalgar South 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.
