Hazard Breakdown
Climate Hazard Breakdown for North Shore
Flood
The North Shore area faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. Several creeks and waterways traverse the region, increasing the potential for inundation.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk is present in areas of the North Shore close to bushland reserves. While not as high as some other regions, the proximity to vegetation poses a threat during dry periods and high winds.
Key drivers:
- ·Dry vegetation
- ·High winds
Heat
The North Shore experiences high temperatures during summer, with potential for heatwaves. Urban areas retain heat, exacerbating the impact on vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Some parts of the North Shore are located near the coast and are exposed to coastal erosion and sea level rise. These areas may experience increased flooding and damage to infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased storm surge
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

Projections based on CSIRO and BOM climate modelling. Scenario: RCP8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 60 | 6.5(+0.5) | 7.0(+1.0) |
| bushfire | 40 | 4.2(+0.2) | 4.5(+0.5) |

Learn moreAbout North Shore's Climate Risk Profile
The North Shore region of Sydney is subject to a range of climate-related risks that are projected to intensify in the coming decades. Flooding is a significant concern due to the presence of numerous waterways and increasing rainfall intensity. Urban development further exacerbates this risk by increasing runoff and reducing natural drainage.
Bushfire risk is present, especially in areas bordering bushland. While not the most significant threat, it requires ongoing vigilance and management, particularly during dry periods. Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations, especially the elderly and those with pre-existing conditions.
Coastal areas of the North Shore are vulnerable to sea level rise and coastal erosion. This can lead to increased flooding, damage to infrastructure, and loss of property value. Planning and adaptation measures are crucial to mitigate these risks.
Addressing these climate risks requires a multi-faceted approach, including reducing greenhouse gas emissions, implementing adaptation measures, and increasing community awareness. Local councils, state government, and individual residents all have a role to play in building a more resilient future for the North Shore.

Frequently Asked Questions
What are the main climate change risks for the North Shore?
The main climate change risks for the North Shore include increased flooding, more frequent and intense heatwaves, bushfire risk in areas near bushland, and coastal erosion in waterfront areas.
How is the council addressing climate change?
North Sydney Council has a climate change strategy that outlines actions to reduce greenhouse gas emissions and adapt to the impacts of climate change. This includes upgrading stormwater infrastructure, implementing heatwave management plans, and promoting sustainable transport.
What can I do to prepare for flooding?
To prepare for flooding, you should check flood maps to understand your property's risk, clear gutters and downpipes, and have an emergency plan in place. Consider installing flood barriers if your property is at high risk.
How can I protect my home from bushfires?
To protect your home from bushfires, clear vegetation around your property, create a defensible space, and have a bushfire survival plan. Ensure your home is well-maintained and that you have adequate insurance coverage.
What are the long-term impacts of sea level rise on the North Shore?
Sea level rise is projected to increase the risk of coastal inundation and erosion in waterfront areas of the North Shore. This could lead to damage to infrastructure, loss of property value, and displacement of residents. Adaptation measures are needed to mitigate these impacts.
