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 Brownsville's Climate Risk Profile
Brownsville, NSW, is a suburb that faces a range of climate-related risks. The primary concerns are flooding and heatwaves, with bushfire risk also present. Climate change is expected to exacerbate these risks in the coming decades.
Flooding is a significant concern due to the suburb's proximity to waterways. Intense rainfall events can lead to both riverine and flash flooding, impacting homes and infrastructure. The risk is projected to increase with climate change, as rainfall intensity is expected to rise.
Heatwaves pose another substantial threat, particularly to vulnerable populations. Rising average temperatures and more frequent heatwaves can lead to heat stress and other health problems. The urban heat island effect may further amplify these risks.
Bushfire risk is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the likelihood of fire. Residents should be aware of bushfire safety measures and have a plan in place.
Coastal risks are relatively low, but sea level rise and coastal erosion are potential long-term concerns. These factors could impact coastal infrastructure and ecosystems.
