Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for McLaren Vale
Flood
McLaren Vale faces a moderate risk of flooding, primarily from local creeks and heavy rainfall events. The risk is projected to increase due to more intense rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The area surrounding McLaren Vale has a notable bushfire risk due to the presence of vineyards and scrubland. Hot, dry summers exacerbate this risk, and climate change is expected to further increase fire danger.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
McLaren Vale experiences high temperatures during summer, leading to heat stress for vulnerable populations. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
McLaren Vale is located inland and has a very low risk of coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Distance from coast
- ·Elevation

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 McLaren Vale's Climate Risk Profile
McLaren Vale, a renowned wine region in South Australia, is increasingly vulnerable to the impacts of climate change. The primary concerns are related to flooding from intense rainfall events, bushfire risk due to dry vegetation and high temperatures, and heatwaves affecting vulnerable populations.
The risk of flooding is driven by the increasing intensity of rainfall events, which can overwhelm local creeks and drainage systems. Urban development in the area may also exacerbate this risk by increasing runoff.
Bushfire risk is a significant concern due to the presence of vineyards and scrubland, which can act as fuel during hot, dry summers. Climate change is expected to increase the frequency and intensity of bushfires, posing a threat to properties and infrastructure.
Heatwaves are becoming more frequent and intense, leading to heat stress for vulnerable populations, particularly the elderly and those with chronic health conditions. Rising average temperatures and the urban heat island effect contribute to this risk.
While McLaren Vale is located inland and has a low risk of coastal hazards, the overall impact of climate change on the region is significant and requires proactive adaptation measures.
