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

- ·Sea level rise
- ·Urban development
coastal Risk
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.
Primary Drivers
- ·Sea level rise
- ·Storm surges
- ·Coastal erosion
bushfire Risk
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.
Primary Drivers
- ·Increased temperatures
- ·Drier conditions
- ·Vegetation dryness
What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase in the future due to increased climate risks.
Price Impact
Properties in flood-prone areas may experience some price impact.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess bushfire risk and implement fire safety measures.
- 3.Consider the potential impacts of sea level rise on coastal properties.
- 4.Evaluate the energy efficiency of the property to mitigate heat risks.
How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

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.
