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 Semaphore Park
Flood
Semaphore Park is at moderate risk of flooding due to its low elevation and proximity to the coast and waterways. Heavy rainfall events can lead to stormwater flooding, and sea level rise increases the risk of coastal inundation.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfire in Semaphore Park is relatively low due to the suburb's coastal location and limited vegetation. However, dry conditions and strong winds can increase the risk during the bushfire season.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Semaphore Park experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. This can impact vulnerable populations and increase energy demand.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Semaphore Park faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. The low-lying coastal areas are particularly vulnerable to inundation during storm surges and high tides.
Key drivers:
- ·Sea level rise
- ·Storm surge

- ·Strong winds
- ·Ignition sources
What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the rising risk of flooding and coastal inundation.
Price Impact
Properties in low-lying areas may experience a decrease in value due to increased flood risk.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's elevation and drainage.
- 3.Inquire about insurance costs and coverage.
- 4.Consider the potential impact of sea level rise on the property.
- 5.Evaluate the property's vulnerability to heatwaves.
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 Semaphore Park's Climate Risk Profile
Semaphore Park, a coastal suburb of Adelaide, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and sea level rise, heatwaves, and coastal erosion. These hazards pose a threat to infrastructure, property values, and the health and safety of residents.
The risk of flooding is exacerbated by the suburb's low elevation and proximity to the coast and waterways. Sea level rise increases the likelihood of coastal inundation during storm surges and high tides. Increased rainfall intensity can also lead to stormwater flooding, particularly in areas with inadequate drainage.
Heatwaves are becoming more frequent and intense, posing a significant health risk to vulnerable populations, such as the elderly and those with chronic health conditions. Rising temperatures also increase energy demand for cooling, placing a strain on the electricity grid.
Coastal erosion is another concern, as rising sea levels and increased storm activity can lead to the loss of beaches and damage to coastal infrastructure. This can impact recreational activities and tourism, as well as property values.
Addressing these climate risks requires a combination of mitigation and adaptation measures. Mitigation efforts focus on reducing greenhouse gas emissions to slow down the rate of climate change. Adaptation measures aim to reduce the vulnerability of the community to the impacts of climate change, such as building flood defenses, improving drainage systems, and implementing heatwave early warning systems.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
