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 Newnham's Climate Risk Profile
Newnham, Tasmania, is a suburb that faces a range of climate-related risks. Its location near the Tamar River estuary makes it particularly vulnerable to flooding and coastal inundation. As sea levels rise and rainfall patterns change, the risk of these events is expected to increase, potentially impacting homes, businesses, and infrastructure.
Bushfire risk is also a concern in Newnham, especially in areas bordering bushland. Hotter, drier conditions can create a more favorable environment for bushfires, increasing the likelihood of outbreaks and the potential for damage. Residents should be aware of bushfire safety measures and take steps to protect their properties.
Heatwaves are another growing threat in Newnham. As temperatures rise, the risk of heat stress and heatstroke increases, particularly for vulnerable populations such as the elderly and those with chronic health conditions. It is important to stay cool and hydrated during heatwaves and to check on neighbors and family members who may be at risk.
Addressing these climate risks will require a coordinated effort from residents, businesses, and local government. This includes investing in infrastructure improvements, implementing adaptation measures, and reducing greenhouse gas emissions. By working together, the community can build resilience and protect Newnham from the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
