Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for St Helens
Flood
St Helens faces a moderate risk of flooding, primarily from heavy rainfall and riverine overflow. The risk is expected to increase with climate change.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in St Helens is moderate due to surrounding vegetation. Drier conditions and higher temperatures are expected to exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier vegetation
Heat
St Helens experiences a relatively low risk from heatwaves compared to other regions, but increasing temperatures are still a concern.
Key drivers:
- ·Rising average temperatures
- ·More frequent heatwaves
Coastal
St Helens is highly vulnerable to coastal hazards due to its location on the coast. Sea level rise and storm surges pose significant threats.
Key drivers:
- ·Sea level rise
- ·Increased storm frequency

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 St Helens's Climate Risk Profile
St Helens, located on the east coast of Tasmania, is particularly vulnerable to coastal hazards due to its low-lying geography and proximity to the ocean. Sea level rise poses a significant threat to coastal infrastructure and properties. Increased storm surges can lead to inundation and erosion, impacting the local community and economy.
Flooding is another significant risk for St Helens, with heavy rainfall events causing riverine flooding and stormwater runoff. Climate change is projected to increase rainfall intensity, leading to more frequent and severe flooding events. This can damage properties, disrupt transportation, and pose risks to public health.
Bushfire risk is moderate in St Helens, with surrounding vegetation posing a potential fire hazard. Drier conditions and higher temperatures are expected to increase the likelihood of bushfires, particularly during the summer months. Residents should be aware of bushfire safety measures and have evacuation plans in place.
While heatwaves are less frequent in St Helens compared to other regions, increasing average temperatures are still a concern. Vulnerable populations, such as the elderly and those with chronic health conditions, may be at risk during periods of extreme heat. It is important to stay hydrated and seek shelter in cool environments during hot weather.
