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 Port Botany
Flood
Port Botany faces a moderate risk of flooding due to its low-lying coastal location and proximity to waterways. Intense rainfall events can lead to stormwater runoff and potential inundation of low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The risk of bushfire in Port Botany is relatively low due to its urbanized environment and limited vegetation. However, nearby industrial areas and potential for grassfires pose a minor threat.
Key drivers:
- ·Dry vegetation
- ·High winds
Heat
Port Botany experiences a high risk of heatwaves due to its urban environment and limited green spaces. High temperatures can pose a significant health risk to vulnerable populations.
Key drivers:
- ·Urban heat island effect
- ·Increased frequency of heatwaves
Coastal
Port Botany faces a moderate risk from coastal hazards due to its proximity to the coastline. Sea level rise and storm surges can lead to coastal erosion and inundation of low-lying areas.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Port Botany's Climate Risk Profile
Port Botany is a suburb in Sydney, New South Wales, known for its industrial and port facilities. The area's low-lying coastal location makes it susceptible to flooding from heavy rainfall and storm surges. Climate change is projected to increase the frequency and intensity of extreme weather events, further exacerbating these risks.
The risk of heatwaves is also a concern in Port Botany due to the urban heat island effect. Limited green spaces and high levels of concrete and asphalt contribute to higher temperatures during summer months. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk during heatwaves.
Coastal erosion and inundation are also potential threats to Port Botany due to sea level rise. The coastline is vulnerable to erosion from wave action and storm surges, which can damage infrastructure and property. Rising sea levels are expected to increase the frequency and severity of these events.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation strategies include improving drainage infrastructure, implementing coastal protection measures, and increasing green spaces to reduce the urban heat island effect. Mitigation efforts focus on reducing greenhouse gas emissions to slow the pace 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.
