Climate Hazard Breakdown for Wallarah
Flood
Wallarah faces a moderate risk of flooding, primarily from heavy rainfall events and potential coastal inundation. The risk is exacerbated by low-lying areas and proximity to waterways.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Wallarah has a moderate bushfire risk due to surrounding bushland. Hot, dry conditions during summer increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Wallarah is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially during summer.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Wallarah faces a moderate risk from coastal hazards, including erosion and inundation, due to its proximity to the coastline and sea level rise.
Key drivers:
- ·Sea level rise
- ·Storm surges

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.
