Climate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 4.0 | 4.3(+0.3) | 4.5(+0.5) |
| bushfire | 3.0 | 3.1(+0.1) | 3.2(+0.2) |
| heat | 7.0 | 7.8(+0.8) | 8.5(+1.5) |
| coastal | 1.0 | 1.0 | 1.0 |
By 2030, Lyneham is projected to experience more frequent and intense heatwaves, increasing the risk of heat stress and infrastructure damage. Flood risk will also increase due to more intense rainfall events.

Learn moreAbout Lyneham's Climate Risk Profile
Lyneham, a suburb of Canberra, is facing increasing climate-related challenges. Rising temperatures and more frequent heatwaves pose a significant threat to the community, particularly vulnerable populations. The urban heat island effect exacerbates these conditions, making it essential to increase green spaces and implement cooling strategies.
Flooding is another concern, with heavy rainfall events and potential stormwater runoff posing a risk to properties and infrastructure. Aging stormwater infrastructure needs upgrades to handle increased rainfall intensity. The suburb's proximity to local waterways also contributes to its flood susceptibility.
Bushfire risk is relatively low due to Lyneham's urban location. However, grassfires in surrounding areas can still pose a threat during dry periods. Maintaining vegetation and implementing fire safety measures are crucial.
While coastal risks are not a direct concern, the broader impacts of climate change, such as disruptions to supply chains and economic activity, can indirectly affect Lyneham. Addressing these challenges requires a comprehensive approach involving government, businesses, and the community.
