Climate Hazard Breakdown for Swanbourne
Flood
Swanbourne has a relatively low flood risk. Most properties are not prone to riverine or flash flooding, but localized heavy rainfall events can cause temporary inundation.
Key drivers:
- ·Rainfall intensity
- ·Drainage capacity
Bushfire
Swanbourne faces a moderate bushfire risk due to its proximity to vegetated areas. While the risk is not extreme, residents should be aware and prepared, especially during dry periods.
Key drivers:
- ·Vegetation density
- ·Temperature
Heat
Swanbourne experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. Vulnerable populations should take precautions during hot weather.
Key drivers:
- ·Global warming
- ·Urban heat island effect
Coastal
Swanbourne is exposed to coastal hazards, including sea level rise and coastal erosion. The suburb's proximity to the coast makes it vulnerable to these impacts, particularly in the long term.
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 Swanbourne's Climate Risk Profile
Swanbourne, Western Australia, faces a range of climate-related risks, with coastal hazards being the most prominent concern. The suburb's location near the coast makes it vulnerable to sea level rise, storm surges, and coastal erosion. These factors could impact property values and infrastructure in the long term.
While the flood risk is relatively low, localized heavy rainfall events can still cause temporary inundation. Residents should ensure their properties have adequate drainage and be aware of flood warnings.
Bushfire risk is moderate, requiring residents to maintain their properties and be prepared for potential bushfire events, especially during dry periods. Staying informed about fire danger ratings and having a bushfire plan is crucial.
Heat risk is increasing, with projections indicating higher average temperatures and more frequent heatwaves. Vulnerable populations, such as the elderly and those with chronic health conditions, should take extra precautions during hot weather.
Overall, Swanbourne requires a proactive approach to climate adaptation, focusing on coastal protection, flood management, bushfire preparedness, and heatwave response.
