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 Holgate
Flood
Holgate faces a moderate risk of flooding due to its proximity to waterways and varied topography. Intense rainfall events can lead to flash flooding, particularly in low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Holgate has a high bushfire risk due to its location surrounded by bushland. Dry conditions and strong winds can exacerbate the risk during the bushfire season.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Holgate experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. Vulnerable populations may be at risk during extreme heat events.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Holgate has a low coastal risk due to its inland location. Sea level rise and coastal erosion are not significant threats to this suburb.
Key drivers:
- ·Distance from coast

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 Holgate's Climate Risk Profile
Holgate, nestled in the Central Coast region of New South Wales, is characterized by its leafy surroundings and proximity to natural bushland. This idyllic setting, however, also presents significant environmental challenges, particularly in the face of a changing climate.
The suburb's location makes it vulnerable to bushfires, with dry vegetation and strong winds creating ideal conditions for fire spread during the bushfire season. Additionally, Holgate experiences moderate flood risk due to its varied topography and proximity to waterways, which can overflow during periods of heavy rainfall.
Rising temperatures and more frequent heatwaves pose another threat to Holgate, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. The urban heat island effect can further exacerbate these risks, especially in areas with limited green space.
While Holgate is not directly exposed to coastal hazards, the broader Central Coast region is vulnerable to sea level rise and coastal erosion, which could indirectly impact the suburb through disruptions to infrastructure and supply chains. Addressing these climate risks requires a coordinated effort from residents, local government, and emergency services to implement adaptation measures and build resilience.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
