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 Avoca
Flood
Avoca faces a moderate risk of flooding due to its proximity to Avoca Lake and coastal location. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Avoca is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Avoca is likely to experience more frequent and intense heatwaves in the future. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Avoca is vulnerable to coastal erosion and inundation due to sea level rise. This can impact coastal infrastructure, properties, and ecosystems.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

Buyer Checklist
- 1.Check flood maps and bushfire prone land maps.
- 2.Assess the property's vulnerability to coastal erosion.

- 4.Consider the cost of insurance and potential increases in the future.
- 5.Evaluate the property's energy efficiency and ability to withstand extreme heat.
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 Avoca's Climate Risk Profile
Avoca, a picturesque suburb on the Central Coast of NSW, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location and proximity to Avoca Lake make it particularly susceptible to flooding and coastal erosion. Rising temperatures and more frequent heatwaves also pose a significant threat to the health and well-being of residents.
Flooding is a major concern for Avoca, with intense rainfall events capable of causing flash flooding and riverine flooding. Sea level rise is exacerbating the risk of coastal inundation, threatening properties and infrastructure along the coastline. The increasing frequency and intensity of storms further compound these risks.
Bushfire risk is moderate, with areas bordering bushland facing a higher threat. Hot, dry conditions and strong winds can quickly escalate bushfire danger, requiring residents to be vigilant and prepared.
Heatwaves are becoming more frequent and intense, posing a significant health risk, especially for vulnerable populations. The urban heat island effect can further amplify temperatures in built-up areas.
Addressing these challenges requires a multi-faceted approach, including investments in flood mitigation infrastructure, coastal protection measures, and community education programs. Residents also need to take individual actions to adapt to the changing climate and reduce their carbon footprint.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
