Overall Risk Score
Confidence: Medium
Hazard Breakdown
Climate Hazard Breakdown for Warragamba
Flood
Warragamba faces a notable risk of flooding due to its proximity to the Warragamba Dam and the Warragamba River. Heavy rainfall events can lead to rapid increases in water levels, posing a threat to properties and infrastructure in low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Dam overflow
Bushfire
The area surrounding Warragamba is characterized by significant bushland, increasing the risk of bushfires, particularly during dry and windy conditions. The risk is exacerbated by climate change, leading to longer fire seasons and more intense fires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Warragamba experiences moderately high temperatures during summer, with the risk of heatwaves increasing due to climate change. This can pose health risks to vulnerable populations, such as the elderly and those with pre-existing conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Warragamba is located inland and does not face any direct coastal risks such as sea level rise or coastal erosion.
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 Warragamba's Climate Risk Profile
Warragamba, located in New South Wales, is exposed to several climate-related risks that are expected to intensify in the coming decades. The primary concerns are flooding due to its proximity to the Warragamba Dam and bushfires due to the surrounding bushland. Rising temperatures also pose a threat, increasing the risk of heatwaves.
The risk of flooding is significant, with potential for increased rainfall intensity and dam overflows. Properties in low-lying areas are particularly vulnerable. Bushfire risk is also high, especially during dry periods, with the potential for fires to spread rapidly through the surrounding vegetation.
Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations. The local council and emergency services are working to mitigate these risks through various strategies, including improved infrastructure and community awareness programs.
Residents should stay informed about weather forecasts and emergency warnings, and take steps to prepare their homes and families for extreme weather events. This includes having an emergency plan, clearing vegetation around properties, and ensuring adequate insurance coverage.
