Hazard Breakdown
Climate Hazard Breakdown for North Bondi
Flood
North Bondi faces a moderate risk of flooding, primarily from heavy rainfall events and coastal inundation. The area's proximity to the coast and low-lying areas contribute to this risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk in North Bondi is relatively low due to its urban environment and limited vegetation. However, nearby parks and reserves can pose a potential threat during extreme weather conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
North Bondi experiences a high risk of heatwaves, particularly during the summer months. Increased urban density and limited green spaces exacerbate the heat island effect.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
North Bondi is highly vulnerable to coastal erosion and sea level rise. The suburb's location directly on the coast makes it susceptible to increased storm surges and inundation.
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 North Bondi's Climate Risk Profile
North Bondi, a coastal suburb in Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include coastal erosion, sea level rise, increased frequency and intensity of heatwaves, and flooding from heavy rainfall events.
Sea level rise poses a significant threat to properties along the coastline. Increased storm surges can lead to inundation and erosion, damaging infrastructure and impacting property values. The suburb's low-lying areas are particularly susceptible to flooding during heavy rainfall, which is expected to become more frequent with climate change.
Heatwaves are becoming more common and intense, posing health risks to vulnerable populations, especially the elderly and those with pre-existing conditions. The urban heat island effect further exacerbates the impact of heatwaves in densely populated areas.
While bushfire risk is relatively low compared to other parts of NSW, nearby parks and reserves can still pose a threat during dry and windy conditions. It is essential to maintain vegetation around properties and be aware of bushfire safety guidelines.
Addressing these climate risks requires a combination of adaptation and mitigation strategies. This includes investing in coastal protection measures, improving stormwater drainage, increasing green spaces to reduce the urban heat island effect, and promoting energy efficiency to reduce greenhouse gas emissions.
