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 Clair's Climate Risk Profile
St Clair, located in New South Wales, is subject to a range of climate-related risks. The primary concerns are flooding and heatwaves, with bushfire risk also being a consideration. The suburb's location and climate patterns contribute to these vulnerabilities.
Flooding is a significant concern due to heavy rainfall events and the presence of nearby waterways. Climate change is projected to increase the intensity and frequency of these events, potentially leading to more widespread flooding in the area. Residents and property owners should be aware of the potential risks and take appropriate precautions.
Heatwaves are another major concern, particularly during the summer months. St Clair experiences high temperatures, and climate change is expected to exacerbate this issue, leading to more frequent and intense heatwaves. This can pose a significant risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Bushfire risk is moderate, with the potential for fires to occur during hot, dry conditions. While not as significant as flooding or heatwaves, it is still important to be aware of the risk and take appropriate precautions, especially during the bushfire season.
Coastal risks are minimal due to St Clair's inland location.
