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 Seaham
Flood
Seaham faces a moderate risk of flooding due to its proximity to the Hunter River and associated tributaries. Heavy rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise impacting drainage
Bushfire
The area around Seaham has a moderate bushfire risk due to surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood and intensity of bushfires.
Key drivers:
- ·Dry vegetation
- ·Increased frequency of heatwaves
Heat
Seaham is likely to experience more frequent and intense heatwaves. Higher average temperatures can pose health risks, especially for vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Seaham has a low coastal risk. While it is not directly on the coast, sea level rise could affect low-lying areas near the Hunter River.
Key drivers:
- ·Sea level rise
- ·Increased storm surge

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to flood and heatwave risks.
Price Impact
Properties in flood-prone areas may experience price stagnation or decline.
Buyer Checklist
- 1.Check flood maps and historical flood data
- 2.Assess property's vulnerability to heatwaves
- 3.Review bushfire risk and prepare a survival plan
- 4.Consider potential impacts of sea level rise on low-lying areas
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 Seaham's Climate Risk Profile
Seaham, located in the Hunter region of New South Wales, is susceptible to a range of climate-related risks. The primary concerns are flooding due to its proximity to the Hunter River, and increasing heatwave frequency and intensity.
Flooding is a significant concern, with potential for both riverine and flash flooding during heavy rainfall events. Climate change is projected to increase rainfall intensity, exacerbating this risk. Sea level rise may also impact drainage in low-lying areas, further increasing flood risk.
Heatwaves are also a growing concern, with projections indicating more frequent and intense heatwaves in the future. This poses health risks, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions.
Bushfire risk is moderate, with surrounding bushland posing a threat during hot, dry conditions. While not as immediate a threat as flooding or heatwaves, residents should still be prepared for bushfire events.
Coastal risks are relatively low, but sea level rise could still impact low-lying areas near the Hunter River. It's important to monitor coastal erosion and storm surge risks in the long term.
