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 Summer Island
Flood
Summer Island faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Summer Island is relatively low due to the lack of extensive bushland. However, increased temperatures and drier conditions could elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Summer Island is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Summer Island faces a moderate risk from coastal hazards due to sea level rise. This could lead to increased erosion and inundation of low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

Detailed Hazard Analysis
heat Risk
Summer Island is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Summer Island faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Inadequate drainage infrastructure
coastal Risk
Summer Island faces a moderate risk from coastal hazards due to sea level rise. This could lead to increased erosion and inundation of low-lying areas.
Primary Drivers
- ·Sea level rise
- ·Increased storm surge
- ·Coastal erosion
bushfire Risk
Bushfire risk in Summer Island is relatively low due to the lack of extensive bushland. However, increased temperatures and drier conditions could elevate the risk.
Primary Drivers
- ·Increased temperatures
- ·Drier conditions
- ·Vegetation dryness

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 Summer Island's Climate Risk Profile
Summer Island is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include more frequent and intense heatwaves, increased flooding due to heavier rainfall and sea level rise, and a potential increase in bushfire risk.
The risk of flooding is driven by the suburb's proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, leading to more frequent and severe flooding events. Sea level rise will further exacerbate this risk, particularly in coastal areas.
Heatwaves are also a significant concern, with rising average temperatures and more frequent heatwave events expected in the future. This poses a particular risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect may also amplify the impact of heatwaves in some areas.
While bushfire risk is currently relatively low, increased temperatures and drier conditions could elevate the risk in the future. It is important for residents to be aware of the potential for bushfires and to take steps to prepare their properties.
Overall, Summer Island faces a range of climate risks that are expected to increase in the coming years. Residents should take steps to prepare for these risks and to reduce their carbon footprint.
