- Flood
- Summer Island faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
- Bushfire
- Bushfire risk in Summer Island is relatively low due to the lack of extensive bushland. However, increased temperatures and drier conditions could elevate the risk.
- Heat
- Summer Island is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Notable storm risk — tropical cyclones and severe thunderstorms in summer months
