Hazard Breakdown
Climate Hazard Breakdown for Bass Hill
Flood
Bass Hill has a moderate risk of flooding due to its proximity to waterways and relatively flat terrain. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Bass Hill is relatively low due to the urbanized nature of the suburb. However, surrounding bushland areas pose a potential threat, especially during dry and windy conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Bass Hill experiences high temperatures during summer, with potential for heatwaves. Climate change is projected to increase the frequency and intensity of heat events, posing risks to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Coastal risks are minimal in Bass Hill due to its distance from the coastline. Sea level rise and coastal erosion are not significant concerns for this suburb.
Key drivers:
- ·Distance from the coast
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 Bass Hill's Climate Risk Profile
Bass Hill, located in New South Wales, is susceptible to several climate-related risks. The suburb's proximity to waterways increases its vulnerability to flooding, which is expected to worsen with climate change due to increased rainfall intensity.
Heatwaves are another significant concern, with rising average temperatures and the urban heat island effect exacerbating the problem. This poses health risks, particularly for elderly and vulnerable residents. Bushfire risk is relatively low but not negligible, especially in areas bordering bushland.
While coastal risks are minimal, the overall climate risk profile suggests the need for proactive adaptation measures. These include improving drainage infrastructure, increasing green spaces to mitigate the urban heat island effect, and implementing community awareness programs to prepare residents for extreme weather events.
Addressing these challenges will require coordinated efforts from local government, emergency services, and the community to build resilience and ensure the long-term sustainability of Bass Hill.
