Climate Hazard Breakdown for Dunsborough
Flood
Dunsborough faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. The risk is expected to increase with climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Dunsborough has a high bushfire risk due to its proximity to bushland and dry vegetation. Hot, dry summers and strong winds exacerbate the risk.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Dunsborough is experiencing more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Global warming
- ·Urban heat island effect
Coastal

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 Dunsborough's Climate Risk Profile
Dunsborough, Western Australia, is a beautiful coastal town that is increasingly vulnerable to the impacts of climate change. The region is experiencing rising temperatures, changes in rainfall patterns, and sea level rise, all of which contribute to increased risks from various hazards.
Bushfire risk is a significant concern for Dunsborough due to the surrounding bushland. Hot, dry summers and strong winds create ideal conditions for bushfires to spread rapidly. Residents need to be prepared for potential evacuations and property damage.
Heatwaves are becoming more frequent and intense, posing a threat to public health, especially for vulnerable populations such as the elderly and young children. Infrastructure can also be affected by extreme heat, leading to power outages and other disruptions.
Flooding is another concern, with heavy rainfall events potentially causing riverine and flash flooding. Sea level rise also increases the risk of coastal inundation, particularly during storm surges.
Coastal erosion is impacting Dunsborough's coastline, threatening beaches, infrastructure, and property. Sea walls and other coastal protection measures may be necessary to mitigate these impacts.
