Hazard Breakdown
Climate Hazard Breakdown for Girraween
Flood
Girraween has a moderate risk of flooding due to its proximity to creeks and drainage systems. Intense rainfall events can lead to flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development reducing permeable surfaces
Bushfire
The risk of bushfire in Girraween is relatively low due to the urban nature of the suburb, but some areas near parks and reserves may be more vulnerable.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Girraween experiences high temperatures during summer, with potential for heatwaves. Urban heat island effect exacerbates the risk.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Girraween is not directly exposed to coastal risks.
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 Girraween's Climate Risk Profile
Girraween, located in the western suburbs of Sydney, is subject to a range of climate-related risks. The most significant of these is flooding, due to the presence of local creeks and drainage systems that can be overwhelmed during periods of heavy rainfall. The increasing intensity of rainfall events, driven by climate change, is expected to exacerbate this risk in the future.
Heatwaves are another major concern for Girraween. The suburb's urban environment contributes to the urban heat island effect, trapping heat and leading to higher temperatures than surrounding areas. This can pose a significant health risk, particularly for vulnerable populations such as the elderly and those with pre-existing medical conditions.
Bushfire risk is relatively low in Girraween compared to other parts of New South Wales, but it is not negligible. Areas near parks and reserves may be more vulnerable, and residents should take precautions to protect their properties.
Coastal risks are minimal in Girraween due to its distance from the coast. However, the broader impacts of climate change, such as sea-level rise and extreme weather events, could still have indirect effects on the suburb.

Frequently Asked Questions
What are the main climate change risks in Girraween?
The main climate change risks in Girraween are increased flooding due to more intense rainfall, and more frequent and severe heatwaves due to rising temperatures and the urban heat island effect.
How can I prepare my home for flooding in Girraween?
You can prepare your home for flooding by elevating appliances, storing valuables above flood level, and having an evacuation plan in place. Check the City of Parramatta Council's flood maps to understand your property's risk.
What is the urban heat island effect, and how does it affect Girraween?
The urban heat island effect is the phenomenon where urban areas experience higher temperatures than surrounding rural areas due to the concentration of buildings, roads, and other infrastructure that absorb and retain heat. This effect exacerbates heatwaves in Girraween.
What is the council doing to address climate change in Girraween?
The City of Parramatta Council is implementing various initiatives to address climate change, including improving stormwater drainage, increasing tree canopy cover, and developing a climate resilience strategy.
Where can I find more information about bushfire risk in Girraween?
You can find more information about bushfire risk in Girraween on the NSW Rural Fire Service website, including bushfire prone area maps and advice on preparing your property.
