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 Thirlmere
Flood
Thirlmere has a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Proximity to waterways
Bushfire
Thirlmere faces a high risk of bushfires due to its location surrounded by bushland. Drier conditions and higher temperatures are expected to exacerbate bushfire risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Thirlmere experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Thirlmere is not directly exposed to coastal risks due to its inland location.

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 Thirlmere's Climate Risk Profile
Thirlmere, located in the Wollondilly Shire, is susceptible to a range of climate-related risks. The primary concerns are flooding due to its proximity to waterways and bushfires due to the surrounding bushland.
Climate change projections indicate an increase in average temperatures and more frequent heatwaves, which will impact the community's health and infrastructure. Rainfall patterns are also expected to change, with more intense rainfall events leading to increased flood risk.
The bushfire risk is particularly concerning, as drier conditions and higher temperatures create a more favorable environment for bushfires to ignite and spread. Residents should maintain their properties and be prepared to evacuate if necessary.
While Thirlmere is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, will still be felt. Adapting to these changes will require a coordinated effort from residents, businesses, and local government.
