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 Grassy Head
Flood
Grassy Head faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Increased rainfall intensity could exacerbate this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfires in Grassy Head is moderate, influenced by surrounding vegetation and dry conditions. Climate change may lead to longer fire seasons and increased fire intensity.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Grassy Head is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.
Key drivers:
- ·Increased temperatures
- ·More frequent heatwaves
Coastal
Grassy Head faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. These factors could impact infrastructure and property values.
Key drivers:
- ·Sea level rise
- ·Coastal erosion

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 Grassy Head's Climate Risk Profile
Grassy Head, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity and sea level rise, more frequent and intense heatwaves, and coastal erosion affecting infrastructure and property.
The risk of flooding is exacerbated by the suburb's proximity to waterways and low-lying areas. Climate change projections indicate an increase in extreme rainfall events, which could lead to more frequent and severe flooding.
Heatwaves are also a growing concern, with projections showing a rise in average temperatures and more frequent heat stress events. This poses a significant risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Coastal erosion and sea level rise threaten coastal infrastructure and property values. The long-term impacts of these hazards could be significant, requiring proactive adaptation measures to protect the community.
Residents and property owners should consider these risks when making decisions about property investment and development. Implementing adaptation strategies, such as improving drainage infrastructure and building resilience to heatwaves, is crucial for mitigating the impacts of climate change in Grassy Head.
