Is Rhyll, VIC Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Rhyll has a moderate flood risk, primarily due to its low-lying coastal position and proximity to tidal waters. While major riverine flooding is unlikely, storm surges and king tides can inundate low-lying areas.
- Bushfire
- Rhyll has a low to moderate bushfire risk. While not directly adjacent to large tracts of dense bushland, surrounding vegetation and the potential for ember attack from nearby areas pose a risk, particularly during hot, dry conditions.
- Heat
- Rhyll experiences a significant heat risk, with a high number of hot days per year and increasing average temperatures. Coastal breezes offer some relief, but prolonged heatwaves can still impact the area.
- Storm
- Moderate storm risk — severe thunderstorms with hail and damaging winds
- Postcode
- 3923
- Highest high-risk exposure
- 19.6% of land (bushfire)
Climate Safety Analysis
Rhyll in Victoria has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Rhyll's climate safety include heat, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Rhyll is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Rhyll including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Rhyll (postcode 3923) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (19.6% of land in high-risk zones), riverine flood (6.4% of land in high-risk zones), surface flood (5.6% of land in high-risk zones). Exposure is not uniform across Rhyll — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
Local Hazard Evidence
Historical Events
Intense rainfall and strong winds caused localized flooding and damage across Phillip Island, with coastal areas experiencing higher water levels.
King tides combined with storm activity led to minor inundation in low-lying coastal areas around Western Port Bay, including sections near Rhyll.
A severe heatwave affected Victoria, with temperatures exceeding 40°C for several consecutive days. Coastal areas like Rhyll experienced significant heat stress.
Significant storm surge event caused coastal erosion and minor inundation along parts of Phillip Island's coast, impacting low-lying areas.

Frequently Asked Questions
Is Rhyll safe from climate change?
No location in Australia is entirely immune to climate change impacts. Rhyll has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Rhyll?
The dominant hazard for Rhyll depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Rhyll compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across Victoria suburbs.
Should I be concerned about buying property in Rhyll?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Rhyll?
Key projections for Victoria from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Rhyll.
What share of Rhyll is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 19.6% of Rhyll in high-risk zones for bushfire, with a further 72.9% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
