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 Merewether Heights's Climate Risk Profile
Merewether Heights, NSW, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, particularly during the dry season. Rising temperatures are expected to lead to more frequent and intense heatwaves, posing health risks to vulnerable residents.
Coastal hazards, including sea level rise and erosion, also present a significant challenge. The suburb's location near the coast makes it susceptible to these impacts, potentially affecting property values and infrastructure.
Flooding is another concern, with increased rainfall intensity potentially leading to more frequent and severe flood events. Urban development and changes in land use can exacerbate these risks.
Addressing these challenges requires a proactive approach, including community education, infrastructure upgrades, and adaptation measures to mitigate the impacts of climate change. Residents should stay informed about local risks and take steps to prepare for extreme weather events.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
