Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Sylvania
Flood
Sylvania faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Sylvania has a moderate bushfire risk due to the presence of nearby bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Decreased rainfall
Heat
Sylvania is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Sylvania faces a moderate risk from coastal hazards due to sea level rise. This includes increased erosion and inundation of low-lying areas.
Key drivers:
- ·Thermal expansion of seawater
- ·Melting glaciers and ice sheets

- 3.Review insurance options and potential premium increases.
- 4.Consider long-term climate projections for the area.
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.
