Climate Hazard Breakdown for Bella Vista
Flood
Bella Vista faces a moderate risk of flooding due to its location within the Parramatta River catchment. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The bushfire risk in Bella Vista is relatively low compared to other areas in NSW, but bushland areas nearby pose a potential threat during dry periods and high winds.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Bella Vista experiences high temperatures during summer, with potential for heatwaves. Urban areas retain heat, exacerbating the impact on vulnerable populations.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Bella Vista is located inland and does not face any direct coastal risks such as sea level rise or coastal erosion.
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 Bella Vista's Climate Risk Profile
Bella Vista, located in the Hills District of Sydney, is a growing residential and commercial area. The suburb's climate is characterized by warm summers and mild winters. However, the region is susceptible to various climate-related hazards.
Flooding is a significant concern due to the suburb's location within the Parramatta River catchment. Intense rainfall events can overwhelm drainage systems and lead to flash flooding, impacting homes and businesses. Climate change is projected to increase the frequency and intensity of these rainfall events, further elevating the flood risk.
Bushfire risk is present due to the proximity of bushland areas. While not as high as some other regions in NSW, dry conditions and strong winds can create a potential fire hazard. Residents should be aware of bushfire safety measures and maintain their properties accordingly.
Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations, particularly the elderly and those with pre-existing health conditions. The urban heat island effect can further amplify temperatures in built-up areas.
Coastal risks are negligible due to Bella Vista's inland location.
