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 Portland
Flood
Portland 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 Portland is bushfire-prone. Hot, dry conditions and nearby bushland contribute to a high bushfire risk, which is expected to worsen with climate change.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Portland experiences moderately high temperatures during summer. Climate change is expected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Portland is not located near the coast, so the risk of coastal hazards is very low.

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 Portland's Climate Risk Profile
Portland, located in the Central Tablelands of New South Wales, is a town with a rich industrial history. However, like many regions in Australia, it is increasingly vulnerable to the impacts of climate change.
The primary climate risks for Portland include bushfires, flooding, and heatwaves. The surrounding bushland creates a significant bushfire threat, particularly during the hot, dry summer months. Climate change is projected to exacerbate these conditions, leading to more frequent and intense bushfires.
Flooding is another concern, with local creeks and heavy rainfall events posing a risk to properties and infrastructure. Increased rainfall intensity due to climate change is expected to increase the frequency and severity of floods.
Heatwaves are also becoming more common and intense, posing a health risk to vulnerable populations, especially the elderly and those with pre-existing health conditions. The town's infrastructure may also be strained during prolonged periods of extreme heat.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing down the rate of climate change. At the local level, measures such as improving building standards, managing bushfire fuel loads, and developing emergency response plans can help to protect the community from the worst impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
