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 Henley Beach
Flood
Henley Beach faces a moderate risk of flooding due to its low-lying coastal location and proximity to the Patawalonga River. Increased rainfall intensity could exacerbate this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Henley Beach is relatively low due to its coastal location and lack of significant vegetation. However, dry conditions and strong winds could increase the risk.
Key drivers:
- ·Dry conditions
- ·Strong winds
Heat
Henley Beach is likely to experience more frequent and intense heatwaves in the future. This could pose 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
Henley Beach faces a moderate risk of coastal erosion and inundation due to sea level rise and storm surge. This could damage coastal infrastructure and property.
Key drivers:
- ·Sea level rise
- ·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 Henley Beach's Climate Risk Profile
Henley Beach, a coastal suburb of Adelaide, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from increased rainfall and storm surge, heatwaves with rising temperatures, and coastal erosion due to sea level rise.
The suburb's low-lying coastal location makes it particularly susceptible to flooding. The Patawalonga River, which flows near Henley Beach, can overflow during heavy rainfall events, inundating nearby properties. Sea level rise is also exacerbating the risk of coastal inundation, especially during storm surges.
Heatwaves are becoming more frequent and intense in South Australia, posing a significant health risk to residents, especially the elderly and those with chronic health conditions. The urban heat island effect can further amplify temperatures in built-up areas.
Coastal erosion is another concern for Henley Beach. Sea level rise is causing increased erosion of the coastline, threatening beaches, dunes, and coastal infrastructure. Protecting the coastline will require ongoing management and adaptation measures.
Addressing these climate risks will require a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is essential to slow the pace of climate change. Local adaptation measures, such as improving drainage infrastructure, implementing heatwave early warning systems, and protecting coastal ecosystems, can help to reduce the impacts of climate change on Henley Beach.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
