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 Gwynneville's Climate Risk Profile
Gwynneville, located in the Wollongong region of New South Wales, is subject to a range of climate-related risks that are projected to intensify in the coming decades. The suburb's proximity to creeks and low-lying areas makes it particularly vulnerable to flooding during periods of heavy rainfall. Climate change is expected to exacerbate this risk through increased rainfall intensity and frequency of extreme weather events.
Bushfire risk is also a concern for Gwynneville, given its proximity to bushland reserves. Hot, dry conditions, coupled with strong winds, can create ideal conditions for bushfires to spread rapidly. While coastal risks are minimal due to its distance from the coastline, the suburb is still indirectly affected by broader climate change impacts.
Rising average temperatures and more frequent heatwaves pose a significant threat to the health and well-being of Gwynneville residents, particularly the elderly and vulnerable populations. The urban heat island effect can further amplify these impacts, leading to higher temperatures in built-up areas.
Addressing these climate risks requires a multi-faceted approach, including investments in flood mitigation infrastructure, bushfire management strategies, and measures to reduce the urban heat island effect. Community awareness and preparedness are also crucial for building resilience to climate change impacts.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
