Confidence: Medium
Hazard Breakdown
Climate Hazard Breakdown for Yowie Bay
Flood
Yowie Bay faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to stormwater runoff and potential inundation.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Yowie Bay is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can elevate the risk during the bushfire season.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Yowie Bay experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. This can impact vulnerable populations and infrastructure.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Yowie Bay faces a moderate coastal risk due to sea level rise and potential erosion. Low-lying areas are vulnerable to inundation during storm surges and high tides.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Learn moreAbout Yowie Bay's Climate Risk Profile
Yowie Bay, located in the Sutherland Shire of New South Wales, is susceptible to a range of climate-related risks. Its proximity to waterways increases the risk of flooding during heavy rainfall events. Climate change is expected to exacerbate these risks, with more intense storms and rising sea levels.
The suburb also faces challenges from increasing temperatures and more frequent heatwaves. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk during these events. The urban environment can amplify the heat island effect, further increasing temperatures.
Bushfire risk is also a concern, especially in areas bordering bushland. Hot, dry conditions and strong winds can create dangerous fire conditions. Residents should be aware of bushfire safety measures and have evacuation plans in place.
Coastal risks, including sea level rise and erosion, pose a threat to low-lying areas of Yowie Bay. These risks are projected to increase in the coming decades, potentially impacting infrastructure and property values. Adaptation measures are needed to mitigate these risks and protect the community.
