Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Chittaway Bay
Flood
Chittaway Bay is susceptible to flooding due to its low-lying areas and proximity to Tuggerah Lake. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity, causing inundation of properties and infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
While not immediately adjacent to dense bushland, Chittaway Bay faces a moderate bushfire risk due to prevailing winds carrying embers from distant fires. Dry vegetation in reserves and parks can also contribute to localized fire hazards.
Key drivers:
- ·Dry vegetation
- ·High winds
Heat
Chittaway Bay experiences increasingly frequent and intense heatwaves during summer. Urban areas retain heat, leading to higher nighttime temperatures and increased heat stress for vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Located near Tuggerah Lake, Chittaway Bay is vulnerable to coastal inundation and erosion due to sea level rise. Increased storm surges can exacerbate these risks, impacting waterfront properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

Detailed Hazard Analysis
heat Risk
Chittaway Bay experiences increasingly frequent and intense heatwaves during summer. Urban areas retain heat, leading to higher nighttime temperatures and increased heat stress for vulnerable populations.
Primary Drivers
- ·Rising average temperatures
- ·Increased frequency of heatwaves
- ·Urban heat island effect
flood Risk
Chittaway Bay is susceptible to flooding due to its low-lying areas and proximity to Tuggerah Lake. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity, causing inundation of properties and infrastructure.
Primary Drivers
- ·Increased rainfall intensity
- ·Sea level rise
- ·Urban development
coastal Risk
Located near Tuggerah Lake, Chittaway Bay is vulnerable to coastal inundation and erosion due to sea level rise. Increased storm surges can exacerbate these risks, impacting waterfront properties and infrastructure.
Primary Drivers
- ·Sea level rise
- ·Increased storm surge
- ·Erosion
bushfire Risk
While not immediately adjacent to dense bushland, Chittaway Bay faces a moderate bushfire risk due to prevailing winds carrying embers from distant fires. Dry vegetation in reserves and parks can also contribute to localized fire hazards.

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 Chittaway Bay's Climate Risk Profile
Chittaway Bay, located on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's low-lying topography and proximity to Tuggerah Lake make it particularly susceptible to flooding from heavy rainfall and rising sea levels. Climate projections indicate that these risks will intensify in the coming decades, potentially leading to significant property damage and disruption to daily life.
Heatwaves are also becoming more frequent and intense in Chittaway Bay, posing a significant health risk to vulnerable populations, such as the elderly and those with chronic illnesses. The urban heat island effect exacerbates these risks, as built-up areas retain more heat than surrounding natural environments. Residents should take precautions to stay cool during heatwaves, such as staying indoors, drinking plenty of water, and using air conditioning.
While the risk of bushfire is moderate, it should not be ignored. Prevailing winds can carry embers from distant fires, and dry vegetation in local reserves can create localized fire hazards. Residents should maintain their properties to reduce the risk of fire spread and be prepared to evacuate if necessary.
Coastal inundation and erosion are also growing concerns for Chittaway Bay. Rising sea levels and increased storm surges can damage waterfront properties and infrastructure, and erode beaches and foreshores. Long-term planning is needed to mitigate these risks and protect the suburb's coastal assets.
