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 North Brother
Flood
North Brother faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. The risk is expected to increase due to climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The suburb is at a high risk of bushfires due to its proximity to bushland. Drier conditions and higher temperatures are expected to exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
North Brother experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This poses a risk to vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
North Brother faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. The risk is projected to increase with climate change.
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 North Brother's Climate Risk Profile
North Brother is exposed to a range of climate-related risks that are expected to intensify in the future. The primary risks include flooding from heavy rainfall and riverine sources, bushfires due to proximity to bushland, heatwaves with increasing average temperatures, and coastal hazards such as sea level rise and erosion.
Flooding is a significant concern, with potential for property damage and disruption to infrastructure. Bushfire risk is elevated due to dry conditions and the presence of flammable vegetation. Heatwaves pose a threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions. Coastal hazards can lead to erosion and inundation of low-lying areas.
Climate change projections indicate that these risks will worsen over time. Increased rainfall intensity is expected to exacerbate flooding, while higher temperatures and drier conditions will increase bushfire risk. Sea level rise will further threaten coastal areas, and heatwaves will become more frequent and intense.
Residents and property owners should take proactive measures to mitigate these risks. This includes preparing emergency plans, maintaining properties to reduce fire hazards, and considering adaptation measures to protect against flooding and coastal erosion. Staying informed about weather forecasts and emergency warnings is also crucial.
