Climate Hazard Breakdown for Bilgola Beach
Flood
Bilgola Beach faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Intense rainfall events can lead to flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The suburb has a moderate bushfire risk due to the presence of surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Bilgola Beach is likely to experience more frequent and intense heatwaves in the future. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Bilgola Beach is vulnerable to coastal erosion and inundation due to sea level rise. This could impact beachfront properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the increasing risk of flooding, bushfires, and coastal erosion.
Price Impact
Properties in high-risk areas may experience a decrease in value as climate risks become more apparent.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Inquire about past flood or bushfire events.
- 4.Consider the cost of insurance and potential for increased premiums.
- 5.Evaluate the property's energy efficiency and ability to withstand extreme weather events.
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 Bilgola Beach's Climate Risk Profile
Bilgola Beach, a picturesque suburb on the Northern Beaches of Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from intense rainfall, bushfires due to dry conditions, heatwaves, and coastal erosion exacerbated by sea level rise.
Flooding is a significant concern due to the suburb's low-lying areas and proximity to waterways. Increased rainfall intensity, driven by climate change, can lead to more frequent and severe flash flooding events. This poses a threat to properties, infrastructure, and the safety of residents.
Bushfire risk is also present, particularly during hot, dry periods. The surrounding bushland can become highly flammable, and strong winds can quickly spread fires. Residents need to be prepared for bushfire emergencies and take steps to protect their properties.
Heatwaves are expected to become more frequent and intense, posing a health risk to vulnerable populations. The elderly, children, and those with chronic health conditions are particularly susceptible to heat stress. Access to cooling and hydration is crucial during heatwaves.
Coastal erosion is another major concern, as sea level rise threatens beachfront properties and infrastructure. Increased storm intensity can also exacerbate erosion. Protecting the coastline and managing coastal development are essential to mitigate these risks.
