Overall Risk Score
Confidence: Medium
Hazard Breakdown
Climate Hazard Breakdown for Long Jetty
Flood
Long Jetty faces a moderate risk of flooding due to its low-lying coastal location and proximity to Tuggerah Lake. Increased rainfall intensity and rising sea levels are expected to exacerbate this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Long Jetty is relatively low compared to other areas in NSW, but some areas near bushland reserves are still vulnerable. Hotter, drier conditions could increase the risk in the future.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Long Jetty is likely to experience more frequent and intense heatwaves in the future. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
As a coastal suburb, Long Jetty is vulnerable to coastal erosion and inundation due to sea level rise. This could impact property values and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity
Wind
Moderate wind risk — East Coast Lows and gust fronts
Storm
Moderate storm risk — severe thunderstorms and hail
Social
Moderate social stability — mixed urban density
Energy
Moderate energy costs — climate-driven cooling demand

Learn moreAbout Long Jetty's Climate Risk Profile
Long Jetty, a suburb on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. Its low-lying coastal location makes it particularly susceptible to flooding and coastal erosion as sea levels rise.
The risk of heatwaves is also increasing, posing a threat to public health, especially for vulnerable populations. The combination of these factors necessitates proactive adaptation measures to protect the community and its assets.
Climate projections indicate that Long Jetty will experience more frequent and intense extreme weather events in the coming decades. This includes heavier rainfall, higher temperatures, and rising sea levels. These changes will exacerbate existing risks and create new challenges for the suburb.
Residents and property owners should take steps to prepare for these changes, such as investing in flood protection measures, improving home cooling, and understanding the risks associated with coastal erosion. The local council is also working to develop strategies to mitigate the impacts of climate change and build a more resilient community.
