Hazard Breakdown
Climate Hazard Breakdown for Gumma
Flood
Gumma faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Climate change
Bushfire
The bushfire risk in Gumma is moderate, with surrounding bushland posing a threat during dry periods and high winds. Grassfires can also be a concern.
Key drivers:
- ·Drier conditions
- ·Increased fuel load
Heat
Gumma is likely to experience more frequent and intense heatwaves, posing a risk to vulnerable populations. Higher average temperatures will increase heat stress.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Coastal risk is low due to Gumma's inland location. Sea level rise and coastal erosion are not significant threats.
Key drivers:
- ·Distance from 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 Gumma's Climate Risk Profile
Gumma, NSW, is a rural locality that is increasingly vulnerable to the impacts of climate change. The primary concerns for Gumma are flooding and heatwaves, with bushfire risk also being a factor.
Flooding is a significant concern due to the potential for intense rainfall events and the proximity of waterways. Climate change is expected to increase the frequency and intensity of these events, placing greater strain on local infrastructure and emergency services. Residents should be aware of flood risks and take appropriate precautions.
Heatwaves are also projected to become more frequent and severe, posing a health risk to vulnerable populations, particularly the elderly and those with pre-existing medical conditions. It is important to stay hydrated, seek shelter in cool environments, and check on neighbors during periods of extreme heat.
Bushfire risk is moderate, with surrounding bushland posing a threat during dry periods and high winds. Residents should maintain their properties to reduce fuel loads and be prepared to evacuate if necessary.
While coastal risks are low due to Gumma's inland location, the community should still be aware of the broader impacts of climate change and support efforts to reduce greenhouse gas emissions.
