Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Tygalgah is located near the Tweed River and is susceptible to flooding from heavy rainfall and riverine overflow. Climate change is expected to increase the frequency and intensity of extreme rainfall events, exacerbating flood risk.
- Bushfire
- Tygalgah has a moderate bushfire risk due to the presence of surrounding vegetation. Hotter, drier conditions associated with climate change are expected to increase the likelihood and severity of bushfires.
- Heat
- Tygalgah is projected to experience more frequent and intense heatwaves due to climate change. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — occasional severe thunderstorms
- Postcode
- 5308
- Highest high-risk exposure
- 10.5% of land (bushfire)
Climate Safety Analysis
Tygalgah 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 Tygalgah's climate safety include heat, flood, coastal. 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 Tygalgah 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.
