Hazard Breakdown
Climate Hazard Breakdown for Coggan
Flood
Coggan faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. The risk is expected to increase due to climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Changes in river flow patterns
Bushfire
The bushfire risk in Coggan is moderate, influenced by surrounding vegetation and dry conditions. Climate change is projected to exacerbate these conditions, leading to a higher frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier vegetation
Heat
Coggan is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations, including the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising average temperatures
- ·More frequent heatwave events
Coastal
Given Coggan's inland location, the risk from coastal hazards such as sea level rise and coastal erosion is very low.
Key drivers:
- ·Distance from the coast
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 Coggan's Climate Risk Profile
Coggan is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from more intense rainfall events, increased frequency and severity of heatwaves, and a moderate risk of bushfires.
The risk of flooding is driven by increased rainfall intensity and changes in river flow patterns. Urban development in the surrounding areas can also exacerbate runoff, increasing the likelihood of flooding. Residents should be aware of flood warnings and have a plan in place to evacuate if necessary.
Heatwaves are becoming more frequent and intense, posing a significant risk to vulnerable populations. It is important to stay hydrated, avoid strenuous activity during the hottest part of the day, and check on elderly neighbors and relatives.
While Coggan is not directly on the coast, the risk of bushfires is still a concern. Residents should maintain their properties to reduce the risk of fire and be aware of bushfire warnings.
Overall, Coggan faces a number of climate-related challenges. By taking steps to prepare for these challenges, residents can protect themselves and their property.
