Climate Hazard Breakdown for Somersby
Flood
Somersby faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. Development and land use changes can exacerbate these risks.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Somersby has a high bushfire risk due to its proximity to extensive bushland areas. Hot, dry conditions and strong winds can significantly increase the likelihood and intensity of bushfires.
Key drivers:
- ·Climate change
- ·Dry vegetation
Heat
Somersby experiences a moderate risk from heatwaves, with increasing average temperatures and more frequent extreme heat events impacting vulnerable populations and infrastructure.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Somersby has a low coastal risk due to its inland location. Coastal hazards such as sea level rise and erosion are not significant concerns for this suburb.

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 Somersby's Climate Risk Profile
Somersby, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, flooding, and heatwaves, which are projected to become more frequent and intense in the coming decades.
Bushfire risk is elevated due to the suburb's proximity to extensive bushland. Hot, dry conditions, coupled with strong winds, create ideal conditions for bushfires to ignite and spread rapidly. Residents should maintain their properties, clear vegetation, and have a bushfire survival plan in place.
Flooding is another significant concern, with heavy rainfall events capable of causing flash flooding and riverine flooding. Changes in land use and development can exacerbate these risks by increasing runoff and reducing natural drainage. Improved stormwater management and flood mitigation infrastructure are essential.
Heatwaves pose a threat to vulnerable populations, including the elderly and those with chronic health conditions. As average temperatures rise, the frequency and intensity of heatwaves are expected to increase, placing additional strain on healthcare services and infrastructure. Simple measures like staying hydrated and seeking cooler environments can help mitigate the impacts of heat.
While coastal risks are low due to Somersby's inland location, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, may still affect the suburb. A proactive approach to climate adaptation is crucial to ensure the long-term resilience and sustainability of Somersby.
