Climate Hazard Breakdown for Wyongah
Flood
Wyongah faces a moderate risk of flooding due to its proximity to Tuggerah Lake and low-lying areas. Intense rainfall events can lead to stormwater runoff and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Wyongah is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the likelihood of fire.
Key drivers:
- ·Dry vegetation
- ·Increased temperatures
Heat
Wyongah experiences a high risk of heatwaves, particularly during summer. Rising temperatures can pose health risks to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Wyongah faces a moderate risk from coastal hazards due to its location near Tuggerah Lake. Sea level rise and storm surges can lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Wyongah's Climate Risk Profile
Wyongah, situated on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to Tuggerah Lake makes it susceptible to flooding, particularly during periods of heavy rainfall and storm surges. Rising sea levels exacerbate this risk, potentially leading to more frequent and severe inundation of low-lying areas.
Heatwaves pose another significant threat to Wyongah, with temperatures expected to rise in the coming decades. This can lead to heat stress and other health problems, especially for elderly residents and those with pre-existing conditions. The urban environment can amplify the effects of heatwaves, creating urban heat islands that further increase temperatures.
Bushfire risk is also present, although less pronounced than flooding and heatwaves. Areas bordering bushland are at greater risk, and residents should take precautions to protect their properties. Changes in vegetation and increased dryness due to climate change could potentially increase the bushfire risk in the future.
Coastal erosion is a concern, particularly along the shores of Tuggerah Lake. Rising sea levels and increased storm intensity can accelerate erosion, threatening infrastructure and property. Careful planning and coastal management strategies are needed to mitigate these risks.
