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 Pennant Hills
Flood
Pennant Hills has a moderate risk of flooding due to its proximity to waterways and potential for heavy rainfall. Properties near creeks and low-lying areas are most vulnerable.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development increasing runoff
Bushfire
Bushfire risk in Pennant Hills is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the risk during bushfire season.
Key drivers:
- ·Dry vegetation
- ·Increased frequency of heatwaves
Heat
Pennant Hills is likely to experience more frequent and intense heatwaves. This can 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
Coastal risk is very low in Pennant Hills due to its distance from the coast. Sea level rise and coastal erosion are not significant concerns.
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 Pennant Hills's Climate Risk Profile
Pennant Hills, located in the upper North Shore of Sydney, is susceptible to several climate-related risks. Flooding is a primary concern due to the presence of creeks and waterways, which can overflow during periods of heavy rainfall. Climate change projections indicate an increase in rainfall intensity, potentially leading to more frequent and severe flood events.
Bushfire risk is also a factor, particularly for properties bordering bushland areas. Hot, dry conditions and strong winds can create a heightened risk of bushfires during the fire season. Residents should maintain their properties and be aware of fire safety guidelines.
Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations. The urban environment can exacerbate the effects of heatwaves, creating an urban heat island effect. It is important to stay hydrated and take precautions during periods of extreme heat.
While coastal risks are minimal due to the suburb's distance from the coast, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, could still affect Pennant Hills. Residents should stay informed about climate change projections and take steps to adapt to the changing environment.
