Hazard Breakdown
Climate Hazard Breakdown for Kogarah Bay
Flood
Kogarah Bay is susceptible to flooding due to its proximity to the bay and low-lying areas. Intense rainfall events can lead to stormwater runoff exceeding drainage capacity, causing inundation of properties and infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Kogarah Bay is relatively low due to its urban environment and limited vegetation. However, nearby bushland areas can pose a threat during extreme weather conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Kogarah Bay 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
As a coastal suburb, Kogarah Bay is vulnerable to sea level rise and coastal erosion. Increased storm surges and inundation can impact properties and infrastructure along the shoreline.
Key drivers:
- ·Sea level rise
- ·Increased storm frequency
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 Kogarah Bay's Climate Risk Profile
Kogarah Bay, located in New South Wales, is a suburb that faces a range of climate-related challenges. Its proximity to the coast and low-lying areas make it particularly vulnerable to the impacts of sea level rise and increased flooding. The urban environment also contributes to the urban heat island effect, exacerbating the impact of heatwaves during summer months.
Flooding is a significant concern for Kogarah Bay, with intense rainfall events leading to stormwater runoff exceeding drainage capacity. This can result in inundation of properties and infrastructure, causing damage and disruption to daily life. Sea level rise further compounds this risk, increasing the likelihood of coastal inundation during high tides and storm surges.
The risk of bushfire in Kogarah Bay is relatively low due to its urban environment and limited vegetation. However, nearby bushland areas can pose a threat during extreme weather conditions. Residents should be aware of the potential for bushfires and take necessary precautions to protect their properties.
Heatwaves are becoming more frequent and intense in Kogarah Bay, posing a significant health risk to vulnerable populations. The urban heat island effect further exacerbates this risk, with built-up areas retaining heat and increasing temperatures. Residents should take steps to stay cool during heatwaves, such as drinking plenty of water, seeking air-conditioned environments, and avoiding strenuous activity.
Addressing these climate risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improving drainage infrastructure, protecting coastal areas, and promoting energy efficiency, can help to reduce the impact of climate change on Kogarah Bay.
