Hazard Breakdown
Climate Hazard Breakdown for Calwell
Flood
Calwell faces a moderate risk of flooding, primarily from heavy rainfall events and localised stormwater runoff. Some areas are more susceptible due to lower elevation and proximity to drainage lines.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Calwell has a relatively high bushfire risk due to its proximity to grassland and bushland areas. Hot, dry summers and strong winds can exacerbate the risk.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Calwell experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. Vulnerable populations are at higher risk.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Calwell is located inland and does not face any direct coastal risks.
Wind
Moderate wind risk — gusty summer winds
Storm
Moderate storm risk — spring/summer thunderstorms
Social
Moderate social stability — high public sector
Energy
Moderate energy costs — heating and cooling

Learn moreAbout Calwell's Climate Risk Profile
Calwell, located in the southern part of Canberra, is a residential suburb with a mix of housing types and green spaces. The suburb's climate is characterized by warm summers and cool winters, with rainfall distributed throughout the year.
Flooding is a concern in some parts of Calwell, particularly during periods of heavy rainfall. The local topography and drainage systems can contribute to localised flooding. Residents should be aware of flood risks and take appropriate precautions.
Bushfire risk is also a factor in Calwell, given its proximity to grassland and bushland areas. During hot, dry summers, the risk of bushfires increases, and residents need to be prepared to respond to bushfire threats.
Heatwaves are becoming more frequent and intense in Canberra, including Calwell. High temperatures can pose health risks, especially for vulnerable populations. Residents should take steps to stay cool and hydrated during heatwave events.
While Calwell is not directly exposed to coastal hazards, the broader impacts of climate change, such as changes in rainfall patterns and increased temperatures, can still affect the suburb.
