Climate Safety Score
5.8Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- The Sydney CBD area faces a moderate risk of flooding due to its location near waterways and the potential for heavy rainfall events. Climate change is expected to increase the intensity of rainfall, potentially exacerbating flood risks.
- Bushfire
- The risk of bushfire in Sydney CBD is relatively low due to the dense urban environment and limited vegetation. However, ember attacks from distant fires remain a potential concern during extreme bushfire weather conditions.
- Heat
- Sydney CBD is subject to significant urban heat island effect, leading to higher temperatures compared to surrounding areas. Climate change is projected to increase the frequency and intensity of heatwaves, posing health risks to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
