- Distance to Bushland
- 5km to Tingalpa Creek Reserve
- Planning Overlay
- Not significantly affected by bushfire overlay
- Bushfire Prone Area
- No
While not a primary concern, bushfire risk can increase during prolonged dry periods due to vegetation in nearby reserves.
Heat Evidence
- Avg January Max Temp
- 30.5°C
- Heat Stress Days/Year
- 3 days
Average maximum temperatures in January are already high, and are projected to increase further with climate change, leading to more frequent heat stress events.
Coastal Evidence

- 0.5 km
- Sea Level Rise Exposure
- Moderate exposure to sea level rise
- Erosion Risk
- Moderate erosion risk along some sections of the coastline

Climate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 7.0 | 7.5(+0.5) | 8.0(+1.0) |
| bushfire | 3.0 | 3.1(+0.1) | 3.3(+0.3) |
| heat | 6.0 | 6.3(+0.3) | 6.7(+0.7) |
| coastal | 7.0 | 7.6(+0.6) | 8.5(+1.5) |
Under a moderate emissions scenario, Wynnum is projected to experience a slight increase in overall climate risk by 2030, with notable increases in flood and coastal risks.

Learn moreAbout Wynnum's Climate Risk Profile
Wynnum, a bayside suburb of Brisbane, is increasingly vulnerable to the impacts of climate change. The suburb's low-lying coastal location makes it particularly susceptible to flooding from heavy rainfall, storm surges, and sea level rise. Rising temperatures are also a concern, with more frequent and intense heatwaves expected in the future.
The primary climate risks for Wynnum include flooding, coastal erosion, and heatwaves. Increased rainfall intensity and sea level rise are expected to exacerbate flooding risks, potentially impacting residential and commercial properties. Coastal erosion poses a threat to beaches and infrastructure along the waterfront.
Rising temperatures will lead to more frequent and intense heatwaves, posing health risks to vulnerable populations, such as the elderly and those with chronic illnesses. The urban heat island effect may further amplify these risks in densely built-up areas.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. Adaptation measures may include improving drainage infrastructure, implementing coastal protection measures, and developing heatwave early warning systems. Mitigation efforts should focus on reducing greenhouse gas emissions to slow the pace of climate change.
Residents and property owners in Wynnum should be aware of the potential climate risks and take steps to protect themselves and their properties. This may include purchasing flood insurance, preparing for heatwaves, and supporting local initiatives to address climate change.
