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 Georges Basin's Climate Risk Profile
St Georges Basin, located in the Shoalhaven region of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location and proximity to St Georges Basin waterway expose it to a range of hazards, including flooding, coastal erosion, and rising sea levels.
Flooding is a significant concern, with intense rainfall events capable of inundating low-lying areas. Climate change is expected to exacerbate this risk, with projections indicating more frequent and intense rainfall in the region. The risk of bushfires is also present due to the surrounding bushland, particularly during dry periods and high winds.
Heatwaves are another growing threat, with St Georges Basin experiencing hot summers. The frequency and intensity of heatwaves are projected to increase, posing health risks to vulnerable populations, especially the elderly and those with pre-existing health conditions.
Coastal erosion and rising sea levels also pose a threat to infrastructure and property in St Georges Basin. The long-term impacts of climate change could lead to significant changes in the coastal environment, affecting property values and the overall livability of the suburb.
