Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Morphett Vale faces a moderate risk of flooding, primarily from heavy rainfall events and the nearby Onkaparinga River. Climate change is expected to increase the frequency and intensity of these events.
- Bushfire
- Bushfire risk in Morphett Vale is relatively low compared to other regions in South Australia, but still present due to nearby bushland areas. Hot, dry summers increase the potential for bushfires.
- Heat
- Morphett Vale is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, especially the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — occasional severe thunderstorms
- Postcode
- 5162
- Highest high-risk exposure
- 9.4% of land (bushfire)
Climate Safety Analysis
Morphett Vale in South 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 Morphett Vale's climate safety include heat. 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 Morphett Vale 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.
