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 Southport
Flood
Southport faces a moderate risk of flooding due to its low-lying coastal location and proximity to the Nerang River. Increased rainfall intensity could exacerbate flood events.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk in Southport is relatively low due to the suburb's urban density and limited vegetation. However, dry conditions and strong winds could increase the risk.
Key drivers:
- ·Dry conditions
- ·Strong winds
Heat
Southport experiences a high heat risk due to its coastal location and urban heat island effect. Increased temperatures and heatwaves could pose a threat to vulnerable populations.
Key drivers:
- ·Rising temperatures
- ·Urban heat island effect
Coastal
Southport faces a moderate risk from coastal hazards, including sea level rise and storm surge. Low-lying areas are particularly vulnerable to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Storm surge

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase in flood-prone areas.
Price Impact
Properties in high-risk areas may experience price stagnation or decline.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's elevation and drainage.
- 3.Inquire about insurance costs and coverage.
- 4.Consider the potential impact of sea level rise and storm surge.
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 Southport's Climate Risk Profile
Southport, located on the Gold Coast, is increasingly vulnerable to the impacts of climate change. The suburb's low-lying coastal geography makes it susceptible to flooding from heavy rainfall and rising sea levels. The urban environment also contributes to a significant urban heat island effect, exacerbating the risks associated with heatwaves.
Flooding is a major concern for Southport residents. The Nerang River and other waterways can overflow during periods of intense rainfall, inundating homes and businesses. Climate change is expected to increase the frequency and intensity of these rainfall events, leading to more severe flooding in the future.
Heatwaves are another significant threat. As temperatures rise, the urban heat island effect will make Southport even hotter than surrounding areas. This can lead to heat stress, particularly for vulnerable populations such as the elderly and those with chronic health conditions.
Coastal hazards, including sea level rise and storm surge, also pose a risk to Southport. Low-lying areas along the coast are vulnerable to inundation and erosion, which could damage property and infrastructure. Planning for these changes is essential to protect the community.
Addressing these climate risks requires a multi-faceted approach. This includes investing in flood mitigation infrastructure, implementing strategies to reduce the urban heat island effect, and planning for sea level rise. Community engagement and education are also crucial to ensure that residents are aware of the risks and prepared to take action.
