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 Narrawallee's Climate Risk Profile
Narrawallee, located on the South Coast of New South Wales, is a beautiful coastal community known for its beaches and natural environment. However, like many coastal areas, Narrawallee is vulnerable to the impacts of climate change.
The suburb faces a number of climate-related risks, including flooding from Narrawallee Creek, bushfires in the surrounding bushland, more frequent and intense heatwaves, and coastal erosion due to sea level rise. These risks are projected to increase in the future, potentially impacting property values and the livability of the area.
Flooding is a significant concern, particularly during periods of heavy rainfall. The low-lying areas around Narrawallee Creek are susceptible to inundation, which can damage homes and businesses. Bushfires also pose a threat, especially during the summer months when conditions are hot and dry.
Rising temperatures are expected to lead to more frequent and intense heatwaves, which can put a strain on the community's infrastructure and health services. Coastal erosion is another major concern, as sea level rise threatens to erode beaches and damage coastal properties.
Addressing these climate risks will require a coordinated effort from residents, businesses, and local government. This includes implementing adaptation measures to reduce the impacts of climate change, such as improving drainage infrastructure, managing bushfire risks, and protecting coastal areas.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
