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 Walla Walla's Climate Risk Profile
Walla Walla, located in the Greater Hume Shire of New South Wales, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, heatwaves, and flooding. Changes in temperature and rainfall patterns are expected to exacerbate these hazards in the coming decades.
Bushfire risk is a significant concern, with the surrounding area containing dry vegetation that can easily ignite during hot and windy conditions. The NSW Rural Fire Service provides resources and information on bushfire preparedness for residents.
Heatwaves are also becoming more frequent and intense, posing a threat to vulnerable populations. Residents should take precautions to stay cool and hydrated during extreme heat events.
Flooding can occur due to heavy rainfall and local creek overflows. It is important for residents to be aware of flood risks and have a plan in place in case of an emergency. The local council provides information on flood management and emergency preparedness.
While Walla Walla is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and economic activity, can still affect 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.
