Climate Hazard Breakdown for Morphett Vale
Flood
Morphett Vale faces a moderate risk of flooding, primarily from heavy rainfall events and the nearby Onkaparinga River. Climate change is expected to increase the frequency and intensity of these events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Morphett Vale is relatively low compared to other regions in South Australia, but still present due to nearby bushland areas. Hot, dry summers increase the potential for bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Morphett Vale is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, especially the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Coastal risks are minimal in Morphett Vale due to its distance from the immediate coastline. Sea level rise and coastal erosion are not direct threats to the suburb.
Key drivers:
- ·Sea level rise
- ·Storm surges

Detailed Hazard Analysis
heat Risk
Morphett Vale is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, especially the elderly and those with pre-existing health conditions.
Primary Drivers
- ·Rising global temperatures
- ·Urban heat island effect
- ·Reduced vegetation cover
flood Risk
Morphett Vale faces a moderate risk of flooding, primarily from heavy rainfall events and the nearby Onkaparinga River. Climate change is expected to increase the frequency and intensity of these events.
Primary Drivers
- ·Increased rainfall intensity
- ·Urban development
- ·Sea level rise affecting river flow
coastal Risk
Coastal risks are minimal in Morphett Vale due to its distance from the immediate coastline. Sea level rise and coastal erosion are not direct threats to the suburb.
Primary Drivers
- ·Sea level rise
- ·Storm surges
bushfire Risk
Bushfire risk in Morphett Vale is relatively low compared to other regions in South Australia, but still present due to nearby bushland areas. Hot, dry summers increase the potential for bushfires.
Primary Drivers

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 Morphett Vale's Climate Risk Profile
Morphett Vale, located in South Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include more frequent and intense heatwaves, increased flooding potential, and, to a lesser extent, bushfire risk.
Heatwaves pose a significant threat to the health and well-being of residents, particularly the elderly and those with chronic health conditions. Rising temperatures and the urban heat island effect exacerbate this risk, leading to increased heat stress and potential for heat-related illnesses.
Flooding is another concern, with the Onkaparinga River and local drainage systems susceptible to overflowing during heavy rainfall events. Climate change is expected to increase the intensity and frequency of these events, potentially leading to property damage and disruption to infrastructure.
While bushfire risk is relatively lower compared to other regions, the presence of nearby bushland areas means that Morphett Vale is not entirely immune. Hot, dry summers increase the potential for bushfires, requiring residents to be vigilant and prepared.
Coastal risks are minimal due to the suburb's distance from the immediate coastline. However, broader climate change impacts, such as sea level rise, could indirectly affect the region through changes in weather patterns and water resources.
