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 Cottesloe
Flood
Cottesloe faces a moderate risk of flooding, primarily from heavy rainfall events and coastal inundation. The risk is exacerbated by low-lying areas near the coast and the presence of drainage systems that can be overwhelmed during intense storms.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Cottesloe is relatively low due to its coastal location and limited vegetation. However, nearby bushland areas pose a potential threat, especially during dry and windy conditions. Embers carried by wind can ignite fires in residential areas.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Cottesloe experiences a high heat risk, with increasing average temperatures and more frequent heatwave events. The urban heat island effect can amplify temperatures in built-up areas, posing health risks to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Cottesloe faces a very high coastal risk due to its location on the coast. Sea level rise, coastal erosion, and storm surges threaten infrastructure, property, and natural ecosystems. The coastline is particularly vulnerable to erosion during extreme weather events.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Premiums are likely to increase due to climate risks.
Price Impact
Properties closer to the coast may experience price reductions.
Buyer Checklist
- 1.Check flood maps and coastal erosion risk assessments.
- 2.Assess property's vulnerability to heatwaves.
- 3.Inquire about insurance coverage and premiums.
- 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.

Learn moreAbout Cottesloe's Climate Risk Profile
Cottesloe, a picturesque coastal suburb in Western Australia, is increasingly vulnerable to the impacts of climate change. The suburb's location on the coast makes it particularly susceptible to sea level rise, coastal erosion, and storm surges. These factors pose a significant threat to infrastructure, property, and the natural environment.
Rising temperatures and more frequent heatwaves are also a major concern for Cottesloe. The urban heat island effect can exacerbate these conditions, leading to increased health risks for vulnerable populations, such as the elderly and those with chronic illnesses. Residents need to be prepared for more extreme heat events and take steps to stay cool and hydrated.
Flooding is another risk factor for Cottesloe, with heavy rainfall events and coastal inundation posing a threat to low-lying areas. The suburb's drainage systems may struggle to cope with increased rainfall intensity, leading to localized flooding and property damage. It is important for residents to understand their flood risk and take appropriate precautions.
While bushfire risk is relatively low compared to other areas, Cottesloe is not entirely immune. Nearby bushland areas can pose a threat during dry and windy conditions, with embers carried by wind potentially igniting fires in residential areas. Residents should maintain their properties and be aware of bushfire safety measures.
