Hazard Breakdown
Climate Hazard Breakdown for Legana
Flood
Legana faces a moderate risk of flooding due to its proximity to the Tamar River and low-lying areas. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfires in Legana is relatively low compared to other regions in Tasmania. However, drier conditions and higher temperatures associated with climate change could increase the risk in the future.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Legana experiences moderate heat risk, with average maximum temperatures in January around 24°C. Climate change is projected to increase the frequency and intensity of heatwaves, potentially impacting vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Legana's coastal areas are exposed to potential impacts from sea level rise and coastal erosion. While the immediate threat is low, long-term projections indicate increasing risks to infrastructure and property.
Key drivers:
- ·Sea level rise
- ·Storm surges
Wind
Notable wind risk — westerly wind storms
Storm
Moderate storm risk — occasional severe weather
Social
Lower social stability — regional isolation
Energy
Moderate energy costs — winter heating

Learn moreAbout Legana's Climate Risk Profile
Legana, Tasmania, is a suburb located on the western bank of the Tamar River. While currently experiencing a relatively mild climate risk profile, the region is projected to face increasing challenges from climate change in the coming decades.
Flooding poses a moderate risk due to the suburb's proximity to the river and low-lying areas. Increased rainfall intensity and potential sea level rise could exacerbate flood events, impacting properties and infrastructure near the river.
Bushfire risk is currently low, but drier conditions and higher temperatures could increase the likelihood of bushfires in the future. Residents should maintain their properties and be aware of fire safety guidelines.
Heatwaves are expected to become more frequent and intense, potentially impacting vulnerable populations. Planning for heatwave events and ensuring access to cooling resources will be important.
Coastal areas may experience increased erosion and inundation due to sea level rise. Long-term planning should consider these potential impacts to protect coastal assets.
