Climate Hazard Breakdown for Dorroughby
Flood
Dorroughby faces a moderate risk of flooding due to its proximity to waterways and undulating terrain. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Changes in land use
Bushfire
Dorroughby has a high bushfire risk due to the surrounding bushland. Dry conditions and strong winds can exacerbate the risk during the bushfire season.
Key drivers:
- ·Drier conditions
- ·Increased fuel load
Heat
Dorroughby experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected in the future.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Dorroughby is not directly exposed to coastal risks due to its inland location.

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 Dorroughby's Climate Risk Profile
Dorroughby, located in New South Wales, is vulnerable to several climate change impacts. The primary risks are associated with increased flooding and bushfire danger. Changes in rainfall patterns and rising temperatures are expected to exacerbate these risks in the coming decades.
Flooding is a significant concern due to the suburb's proximity to waterways and its topography. Intense rainfall events can overwhelm drainage systems and lead to property damage. Bushfire risk is elevated due to the surrounding bushland, which can become dry and highly flammable during the fire season.
Heatwaves are also expected to become more frequent and intense, posing a risk to vulnerable populations. While Dorroughby is not directly exposed to coastal hazards, the broader region may experience indirect impacts from sea-level rise and coastal erosion.
Adapting to these changes will require a combination of individual actions, community initiatives, and government policies. Residents should take steps to protect their properties and prepare for extreme weather events. Local authorities need to invest in infrastructure improvements and implement effective land management practices.
