Flood
Wynnum faces a notable flood risk due to its low-lying coastal location and proximity to waterways. Heavy rainfall events can lead to stormwater and riverine flooding.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk in Wynnum is relatively low due to the suburb's coastal location and limited vegetation. However, dry conditions and strong winds can increase the risk.
Key drivers:
- ·Dry vegetation
- ·Strong winds
Heat
Wynnum experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves. Vulnerable populations are at higher risk during extreme heat events.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
As a coastal suburb, Wynnum is highly vulnerable to coastal hazards such as sea level rise, storm surge, and coastal erosion. These hazards can impact infrastructure, property, and ecosystems.

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, a charming bayside suburb of Brisbane, is increasingly vulnerable to the impacts of climate change. Its low-lying coastal location makes it particularly susceptible to rising sea levels and storm surges, which can lead to increased flooding and coastal erosion. The suburb also faces challenges from more frequent and intense heatwaves, impacting vulnerable populations and infrastructure.
Flooding is a significant concern for Wynnum, with heavy rainfall events causing stormwater and riverine flooding. Climate change is expected to exacerbate this risk, with more intense rainfall and rising sea levels increasing the frequency and severity of floods. This can lead to property damage, disruption to transportation, and potential health risks.
Heatwaves are also becoming more common and intense in Wynnum, posing a threat to public health, especially for the elderly, children, and those with chronic illnesses. The urban heat island effect can further amplify these impacts, making it essential to implement strategies to mitigate heat risks.
Coastal hazards, such as sea level rise and storm surge, pose a long-term threat to Wynnum's coastal areas. These hazards can lead to erosion of beaches and foreshores, damage to coastal infrastructure, and loss of coastal ecosystems. Protecting and restoring coastal habitats can help to buffer against these impacts.
Addressing these climate risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improving drainage infrastructure, promoting green infrastructure, and raising awareness about climate risks, can help to build resilience and protect Wynnum's community and assets.
