Climate Safety Score
5.8Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Swansea is located near Lake Macquarie and the ocean, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.
- Bushfire
- Swansea has some areas of bushland interface, increasing the risk of bushfires. Hotter and drier conditions due to climate change are expected to lengthen the bushfire season and increase the intensity of fires.
- Heat
- Swansea is projected to experience more frequent and intense heatwaves due to climate change. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2281
Climate Safety Analysis
Swansea in New South Wales 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 Swansea'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 Swansea 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.
