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.

About Diamond Creek's Climate Risk Profile

Diamond Creek, located in the Nillumbik Shire, is a suburb that will experience the effects of climate change in the coming decades. The primary risks are associated with increased flooding, bushfire danger, and more frequent heatwaves.

The risk of flooding is elevated due to the suburb's location near Diamond Creek and other waterways. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flooding events. This poses a threat to properties located near the creek and low-lying areas.

Bushfire risk is also a significant concern for Diamond Creek. The suburb is surrounded by bushland, which creates a high fuel load. As temperatures rise and conditions become drier, the risk of bushfires will increase. Residents need to be prepared for potential evacuations and property damage.

Heatwaves are expected to become more frequent and intense in Diamond Creek. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions. It is important to take measures to stay cool during heatwaves, such as drinking plenty of water and spending time in air-conditioned environments.

While Diamond Creek is not directly exposed to coastal risks, the broader impacts of climate change, such as economic disruption and displacement of populations, could indirectly affect the suburb.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
