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 Karratha
Flood
Karratha faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Karratha is located in a region with a high bushfire risk due to dry vegetation and hot, windy conditions. The risk is exacerbated by climate change.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Karratha experiences extreme heat, with average maximum temperatures frequently exceeding 40°C. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Karratha is vulnerable to coastal hazards such as sea level rise and storm surge. These hazards can lead to inundation of low-lying areas and erosion of coastlines.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to climate risks.
Price Impact
Properties in high-risk areas may experience price reductions.
Buyer Checklist
- 1.Check flood maps and bushfire-prone area designations.
- 2.Assess the property's vulnerability to coastal hazards.
- 3.Consider the cost of insurance and potential for increased premiums.
- 4.Evaluate the property's energy efficiency and ability to withstand extreme heat.
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 Karratha's Climate Risk Profile
Karratha is a coastal town in the Pilbara region of Western Australia, known for its mining industry and proximity to natural attractions. However, the region is also vulnerable to a range of climate hazards, including bushfires, heatwaves, flooding, and coastal erosion.
Climate change is expected to exacerbate these risks in the coming decades. Rising temperatures will increase the frequency and intensity of heatwaves, making it more difficult to live and work in the region. Drier conditions will increase the risk of bushfires, threatening lives, property, and infrastructure.
Sea level rise and storm surge will inundate low-lying coastal areas, damaging homes, businesses, and critical infrastructure. Intense rainfall events will lead to flash flooding, disrupting transportation and causing property damage.
Addressing these climate risks will require a concerted effort from government, industry, and the community. This includes investing in adaptation measures such as building seawalls, improving drainage systems, and implementing bushfire management strategies. It also requires reducing greenhouse gas emissions to mitigate the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
