Projections based on CSIRO and BOM climate modelling. Scenario: RCP4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 7.5 | 7.9(+0.4) | 8.5(+1.0) |
| bushfire | 3.0 | 3.1(+0.1) | 3.5(+0.5) |
| heat | 6.0 | 6.3(+0.3) | 6.8(+0.8) |
| coastal | 6.5 | 7.0(+0.5) | 7.7(+1.2) |
Under a moderate emissions scenario, Cairns is projected to experience a slight increase in overall climate risk by 2030. Flooding and coastal risks are expected to increase due to sea level rise and more intense rainfall events. Heat risk will also rise due to increasing temperatures.

Learn moreAbout Cairns's Climate Risk Profile
Cairns, located in Far North Queensland, is highly vulnerable to the impacts of climate change. The region's tropical climate already brings high temperatures and humidity, which are expected to worsen with rising global temperatures. Sea level rise poses a significant threat to coastal areas, increasing the risk of inundation and erosion.
Flooding is a major concern in Cairns due to its location in a tropical cyclone region and proximity to rivers and creeks. Heavy rainfall events can lead to both riverine and flash flooding, disrupting transportation and damaging property. Climate change is projected to increase the intensity of rainfall events, exacerbating the risk of flooding.
Bushfire risk is moderate in Cairns, with some areas bordering bushland being more vulnerable. Drier conditions and increased temperatures can increase the likelihood of bushfires. Residents should be aware of bushfire safety measures and prepare their properties accordingly.
Coastal hazards, including storm surges and coastal erosion, are also a concern in Cairns. Sea level rise is expected to increase the frequency and severity of these events, threatening coastal infrastructure and ecosystems. Adaptation measures, such as seawalls and beach nourishment, may be necessary to protect vulnerable areas.
Overall, Cairns faces a complex set of climate risks that require proactive adaptation and mitigation strategies. Residents, businesses, and government agencies must work together to build a more resilient community.
