Overall Risk Score
Hazard Breakdown
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 Mount Lewis
Flood
Mount Lewis faces a moderate risk of flooding due to its proximity to local waterways and drainage infrastructure. Intense rainfall events can lead to localised flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The bushfire risk in Mount Lewis is relatively low due to the urban nature of the suburb. However, proximity to green spaces and parks can pose a risk during dry periods.
Key drivers:
- ·Vegetation density
- ·Temperature
Heat
Mount Lewis is susceptible to heatwaves, particularly during the summer months. Urban heat island effect can exacerbate the impact of high temperatures.
Key drivers:
- ·Increased frequency of heatwaves
- ·Urban density
Coastal
Coastal risks are minimal in Mount Lewis due to its distance from the coastline. Sea level rise and coastal erosion are not direct threats.
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 Mount Lewis's Climate Risk Profile
Mount Lewis, located in the Canterbury-Bankstown region of Sydney, is primarily an urban residential area. The suburb's climate risks are influenced by its geographical location and urban environment.
Flooding is a notable concern due to the presence of local waterways and the potential for heavy rainfall events. The existing drainage infrastructure may be insufficient to handle increased rainfall intensity, leading to localised flooding.
Heatwaves pose a significant threat, particularly during the summer months. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can amplify the impact of high temperatures, affecting vulnerable populations.
Bushfire risk is relatively low compared to other areas in NSW, but the proximity to parks and green spaces means that residents should remain vigilant during dry periods. Coastal risks are minimal due to the suburb's distance from the coast.
Climate change projections indicate an increase in the frequency and intensity of extreme weather events, including heatwaves and heavy rainfall. Residents and local authorities need to implement adaptation measures to mitigate these risks and protect the community.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
