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 Wynnum
Flood
Wynnum faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Wynnum is relatively low due to the lack of extensive bushland areas. However, dry vegetation and strong winds can still pose a threat during the fire season.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Wynnum experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves expected due to climate change. This can impact vulnerable populations and infrastructure.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Wynnum faces a moderate coastal risk due to potential sea level rise and coastal erosion. This could impact coastal infrastructure and ecosystems.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Wynnum's Climate Risk Profile
Wynnum is a suburb in South Australia that is exposed to several climate-related risks. The most significant risks are flooding, heatwaves, and coastal hazards. Climate change is expected to exacerbate these risks in the coming decades.
Flooding is a concern due to the suburb's proximity to waterways and low-lying areas. Increased rainfall intensity and sea level rise will likely increase the frequency and severity of flood events. This could damage property, disrupt infrastructure, and pose risks to human safety.
Heatwaves are also a growing concern, with average temperatures expected to rise and heatwaves becoming more frequent and intense. This can lead to heat stress, particularly for vulnerable populations such as the elderly and those with chronic health conditions. Infrastructure, such as power grids, may also be strained during extreme heat events.
Coastal risks, including sea level rise and coastal erosion, pose a threat to coastal infrastructure and ecosystems. These risks could impact property values and recreational areas.
Residents and businesses in Wynnum should take steps to prepare for these climate-related risks. This includes implementing flood mitigation measures, improving building resilience to heat, and planning for potential disruptions from extreme weather events.
