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 Gymea Bay
Flood
Gymea Bay is susceptible to flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to stormwater runoff and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The suburb has a moderate bushfire risk due to the presence of surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Gymea Bay is likely to experience more frequent and intense heatwaves in the future. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Sea level rise poses a threat to coastal areas of Gymea Bay, potentially leading to increased erosion and inundation. Low-lying properties are particularly vulnerable.
Key drivers:
- ·Thermal expansion of seawater
- ·Melting glaciers and ice sheets

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 Gymea Bay's Climate Risk Profile
Gymea Bay, located in the Sutherland Shire, is exposed to a range of climate-related risks. Its proximity to waterways makes it vulnerable to flooding, particularly during periods of heavy rainfall. Climate change is expected to exacerbate this risk, with more intense storms and rising sea levels.
Bushfire risk is also a concern, given the presence of surrounding bushland. While not as high as some other areas, the potential for bushfires remains, especially during hot, dry summers. Residents should maintain their properties and be aware of fire safety guidelines.
Heatwaves are becoming more frequent and intense, posing a significant health risk to vulnerable populations. The urban environment can amplify the effects of heat, making it essential to take precautions during extreme heat events.
Coastal hazards, such as sea level rise and erosion, also present a challenge. Low-lying areas are at risk of inundation, and coastal infrastructure may be vulnerable to damage. Long-term planning is needed to address these risks and protect coastal communities.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
