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.

About Ventnor's Climate Risk Profile

Ventnor, situated on the southern coast of Phillip Island in Victoria, presents a complex climate risk profile for its residents. The suburb's geographical position directly exposes it to the full force of coastal weather systems, making coastal erosion and inundation the most significant climate-related threats. With sea levels projected to rise and storm intensity increasing, the risk of coastal inundation during extreme weather events is expected to escalate.

The bushfire risk in Ventnor is generally considered low to moderate. While the suburb is not surrounded by dense, continuous bushland, pockets of vegetation and its proximity to rural areas mean that the potential for bushfire ignition and spread exists, particularly during prolonged dry periods. Fire management strategies and awareness remain important for residents in these areas.

Heat stress is another growing concern for Ventnor. As global temperatures rise, the frequency and intensity of heatwaves are predicted to increase. Coastal breezes may offer some respite, but prolonged periods of extreme heat can still pose significant health risks, particularly to vulnerable populations. The urban heat island effect, though less pronounced than in major cities, can also contribute to higher temperatures within the suburb.

Flood risk, while distinct from coastal inundation, is also a factor. Low-lying areas and proximity to coastal drainage systems can be susceptible to flooding during intense rainfall events, especially when combined with high tides or storm surges. Understanding local drainage patterns and potential flood pathways is crucial for property owners.

In summary, Ventnor's climate risk is dominated by its coastal exposure. While other hazards like bushfire and heat require ongoing vigilance, the long-term challenges posed by sea level rise and increased storm activity necessitate proactive adaptation and planning for the community.

Frequently Asked Questions

What is the main climate risk for Ventnor?

The primary climate risk for Ventnor is coastal erosion and inundation due to its location on Phillip Island's southern coast, exposed to the Southern Ocean. Sea level rise and increased storm intensity are exacerbating these risks.

How will sea level rise affect Ventnor?

Sea level rise is projected to increase the frequency and severity of coastal inundation during high tides and storm surges, leading to greater erosion of beaches and foreshore areas. This could impact properties close to the coast.

Is Ventnor prone to bushfires?

Ventnor has a low to moderate bushfire risk. While not surrounded by dense forests, some areas border vegetation and coastal scrub, and the suburb is designated as a Bushfire Prone Area. Residents should maintain fire preparedness.

What can I do to protect my property from coastal erosion in Ventnor?

For properties directly threatened, consider consulting with coastal engineers about protection measures. For most residents, maintaining vegetation, adhering to building setbacks, and staying informed about council and state coastal management plans are key.

Are there specific heatwave risks for Ventnor residents?

Yes, like much of Victoria, Ventnor is experiencing more frequent and intense heatwaves. Coastal breezes may offer some relief, but prolonged periods of high temperatures can still pose health risks, especially for the elderly and those with pre-existing conditions. Staying hydrated and seeking cool environments is important.

Where can I find official flood maps for Ventnor?

Official flood information, including maps and overlays, can typically be found on the Bass Coast Shire Council's website under their planning and environment sections, or through state agencies like DELWP.
