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 Brighton
Flood
Brighton faces a moderate risk of flooding, primarily from heavy rainfall events and coastal inundation. The Patawalonga River and proximity to the coast increase vulnerability.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Brighton is relatively low due to its coastal location and limited vegetation. However, dry conditions and strong winds can elevate the risk.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Brighton experiences a high risk of heatwaves, particularly during the summer months. Increased temperatures can pose a threat to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Brighton faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. The coastline is vulnerable to storm surges and rising sea levels.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Brighton's Climate Risk Profile
Brighton, a coastal suburb of Adelaide, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and coastal inundation, heatwaves during the summer months, and coastal erosion due to sea level rise.
The Patawalonga River, which flows through Brighton, increases the risk of flooding during periods of heavy rainfall. Coastal areas are susceptible to inundation from storm surges and rising sea levels. The increasing frequency and intensity of extreme weather events are exacerbating these risks.
Heatwaves pose a significant threat to vulnerable populations, such as the elderly and those with chronic health conditions. Rising average temperatures and the urban heat island effect contribute to the severity of heatwaves in Brighton.
Coastal erosion is an ongoing concern, with sea level rise threatening to further erode the coastline and damage infrastructure. Protecting the coastline and managing coastal development are crucial for mitigating these risks.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. This includes investing in flood defenses, implementing heatwave early warning systems, and promoting sustainable coastal development. Community engagement and awareness are also essential for building resilience to 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.
