Hazard Breakdown
Climate Hazard Breakdown for South Windsor
Flood
South Windsor is highly susceptible to flooding due to its proximity to the Hawkesbury River and low-lying areas. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
South Windsor faces a moderate bushfire risk due to surrounding bushland. Hotter, drier conditions driven by climate change are projected to lengthen the bushfire season and increase fire intensity.
Key drivers:
- ·Increased temperatures
- ·Drier vegetation
Heat
South Windsor experiences high temperatures during summer, and climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
South Windsor is not directly exposed to coastal hazards, but sea level rise may indirectly affect the region through increased riverine flooding.
Key drivers:
- ·Sea level rise
- ·Storm surge
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 South Windsor's Climate Risk Profile
South Windsor, located in the Hawkesbury region of New South Wales, is increasingly vulnerable to the impacts of climate change. The most pressing concern is the escalating risk of flooding, driven by more intense rainfall events and potential sea level rise affecting the Hawkesbury River.
Bushfire risk is also a factor, with hotter and drier conditions lengthening the fire season and increasing the intensity of potential fires. The surrounding bushland contributes to this risk, requiring residents to be vigilant and prepared.
Heatwaves are becoming more frequent and severe, posing a threat to vulnerable populations, especially during the summer months. The urban environment can exacerbate the effects of heat, making it essential to implement strategies to mitigate heat stress.
While not directly on the coast, South Windsor may experience indirect impacts from sea level rise through increased riverine flooding. Adapting to these changes will require a coordinated effort from residents, local government, and emergency services.
