Flood
Broadbeach faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater inundation and riverine flooding.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The risk of bushfire in Broadbeach is relatively low due to its urban development and limited vegetation. However, dry conditions and strong winds can increase the risk.
Key drivers:
- ·Dry conditions
- ·Strong winds
Heat
Broadbeach experiences high temperatures and humidity during summer, leading to heat stress. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Rising temperatures
- ·Urban heat island effect
Coastal
Broadbeach is highly vulnerable to coastal hazards such as sea level rise, storm surge, and coastal erosion. These hazards can damage infrastructure, property, and ecosystems.
Key drivers:
- ·Sea level rise
- ·Storm surge

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 Broadbeach's Climate Risk Profile
Broadbeach, located on the Gold Coast, is a popular tourist destination known for its beaches, shopping, and entertainment. However, the suburb is increasingly vulnerable to the impacts of climate change.
Flooding is a significant concern due to the suburb's low-lying coastal location and proximity to waterways. Intense rainfall events can overwhelm stormwater drainage systems and cause widespread inundation. Sea level rise is exacerbating the risk of coastal flooding and erosion.
Heatwaves are becoming more frequent and intense, posing a threat to public health, especially for vulnerable populations. The urban heat island effect further amplifies temperatures in built-up areas.
Coastal hazards such as storm surge and coastal erosion are also major threats. Sea level rise is increasing the vulnerability of coastal infrastructure and property to damage from these events.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation strategies include improving stormwater drainage, building seawalls, and implementing heatwave early warning systems. Mitigation efforts focus on reducing greenhouse gas emissions to slow the pace of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
