Is Noarlunga, SA Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Noarlunga faces a moderate risk of flooding, primarily from the Onkaparinga River and heavy rainfall events. The risk is expected to increase with climate change due to more intense rainfall.
- Bushfire
- The bushfire risk in Noarlunga is relatively low compared to other areas in South Australia, but still present due to nearby vegetation. Hotter, drier conditions are projected to increase this risk.
- Heat
- Noarlunga experiences a high heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses a significant threat to vulnerable populations.
- Storm
- Moderate storm risk — occasional severe thunderstorms
Climate Safety Analysis
Noarlunga 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 Noarlunga'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 Noarlunga 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.
