Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
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

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

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.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
