Climate Hazard Breakdown for Gwandalan
Flood
Gwandalan faces a moderate risk of flooding due to its proximity to Lake Macquarie and low-lying areas. Intense rainfall events can lead to stormwater and lake flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Rising lake levels
Bushfire
The risk of bushfire in Gwandalan is moderate, with bushland areas surrounding the suburb. Hot, dry conditions and strong winds can increase the likelihood of fire.
Key drivers:
- ·Dry vegetation
- ·Hotter temperatures
Heat
Gwandalan is likely to experience more frequent and intense heatwaves. High humidity levels can exacerbate the effects of heat, posing a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Gwandalan faces a moderate risk from coastal hazards due to its location on the shores of Lake Macquarie. Sea level rise and storm surges can lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

Detailed Hazard Analysis
heat Risk
Gwandalan is likely to experience more frequent and intense heatwaves. High humidity levels can exacerbate the effects of heat, posing a risk to vulnerable populations.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Gwandalan faces a moderate risk of flooding due to its proximity to Lake Macquarie and low-lying areas. Intense rainfall events can lead to stormwater and lake flooding.
Primary Drivers
- ·Increased rainfall intensity
- ·Rising lake levels
- ·Inadequate drainage infrastructure
coastal Risk
Gwandalan faces a moderate risk from coastal hazards due to its location on the shores of Lake Macquarie. Sea level rise and storm surges can lead to inundation and erosion.
Primary Drivers

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 Gwandalan's Climate Risk Profile
Gwandalan, situated on the shores of Lake Macquarie, is exposed to a range of climate-related risks. The suburb's low-lying areas make it particularly vulnerable to flooding from intense rainfall and rising lake levels. Climate change is projected to increase the frequency and intensity of extreme rainfall events, potentially leading to more severe flooding in the future.
The risk of bushfire is also a concern, with bushland areas surrounding the suburb. Hot, dry conditions and strong winds can create a high fire danger, threatening homes and properties. Residents should be aware of bushfire safety measures and have a plan in place in case of an emergency.
Heatwaves are becoming more frequent and intense in Gwandalan, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. High humidity levels can exacerbate the effects of heat, making it even more important to stay cool and hydrated during hot weather.
Finally, Gwandalan faces a moderate risk from coastal hazards due to its location on Lake Macquarie. Sea level rise and storm surges can lead to inundation and erosion, potentially damaging property and infrastructure. Long-term planning is needed to address these risks and protect the suburb from the impacts of climate change.
