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 Northam's Climate Risk Profile
Northam, located in the Wheatbelt region of Western Australia, is susceptible to several climate-related hazards. The town's proximity to the Avon River increases its vulnerability to flooding, particularly during periods of heavy rainfall. Climate change is projected to increase the intensity and frequency of extreme rainfall events, potentially leading to more severe flooding in the future.
Bushfire risk is also a concern for Northam, as the surrounding landscape includes areas of bushland that can become highly flammable during the hot, dry summer months. Rising temperatures and prolonged droughts, driven by climate change, are expected to further elevate the risk of bushfires in the region.
Heatwaves pose a significant threat to the health and well-being of Northam residents, especially the elderly and those with pre-existing medical conditions. The town experiences high temperatures during summer, and climate change is projected to lead to more frequent and intense heatwaves in the future. This will place increased strain on the local healthcare system and require adaptation measures to protect vulnerable populations.
While Northam is located inland and does not face direct coastal risks, the broader impacts of climate change, such as disruptions to agriculture and water resources, could indirectly affect the town and its economy. Addressing these challenges will require a coordinated effort involving local government, community organizations, and individual residents.
