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 Wannanup's Climate Risk Profile
Wannanup, located in the City of Mandurah, Western Australia, is a coastal community with unique environmental characteristics. The suburb's proximity to the coast makes it vulnerable to sea level rise and coastal erosion. Climate change projections indicate an increase in the frequency and intensity of extreme weather events, posing significant challenges to the region.
Flooding is a concern due to heavy rainfall and storm surges, which can inundate low-lying areas. Bushfire risk is present due to the surrounding bushland, with hot, dry summers increasing the likelihood of fires. Heatwaves are becoming more frequent and intense, impacting public health and infrastructure.
Coastal hazards, including erosion and inundation, threaten coastal properties and infrastructure. Sea level rise is expected to exacerbate these risks, potentially leading to significant property damage and displacement.
Addressing these climate risks requires a coordinated effort from local government, residents, and businesses. Implementing adaptation measures, such as improved drainage systems, bushfire management strategies, and coastal protection measures, is crucial to building resilience and protecting the community.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
