Historical Climate Events
The Black Saturday bushfires impacted the broader Gippsland region, including areas near Narracan, causing widespread destruction and loss of life. While Narracan itself may have been spared direct major impact, the regional event highlighted the extreme bushfire threat.
SourceSignificant rainfall led to localised flooding in parts of the Baw Baw Shire, affecting roads and properties. Narracan experienced some disruption due to swollen creeks and saturated ground.
SourceVictoria experienced a severe heatwave with prolonged periods above 40°C. While specific data for Narracan is limited, the region endured extreme temperatures, impacting health and increasing fire danger.
SourceHeavy rainfall across Gippsland caused localised flooding, impacting roads and properties in low-lying areas. Narracan experienced minor disruptions due to creek flooding.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP 4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 60 | 6.5(+0.5) | 6.8(+0.8) |

Learn moreAbout Narracan's Climate Risk Profile
Narracan, located in Victoria's Gippsland region, presents a complex climate risk profile, with bushfire being the most prominent concern. The suburb is nestled amongst significant bushland areas, increasing its vulnerability during periods of high fire danger. Climate change projections indicate an increase in the frequency and intensity of extreme heat events, coupled with drier vegetation, which collectively elevate the bushfire risk.
The flood risk in Narracan, while currently assessed as moderate, is influenced by localised heavy rainfall and the potential for creek overflows. As rainfall patterns shift towards more intense, shorter bursts, the capacity of existing drainage systems may be challenged, leading to increased flash flooding potential. Understanding the specific catchment dynamics and stormwater infrastructure is crucial for managing this risk.
Heatwaves pose a growing threat to Narracan. The number of days exceeding 35°C is expected to rise, impacting public health, infrastructure, and local ecosystems. While Narracan is not heavily urbanised, the general trend of rising temperatures and more frequent extreme heat events necessitates adaptation strategies focused on cooling and health.
Coastal hazards are not a direct concern for Narracan due to its inland location. However, broader regional climate impacts, such as changes in water availability or agricultural productivity, could indirectly affect the community. The focus for Narracan remains on managing terrestrial risks like bushfire and flood.
Overall, Narracan requires a proactive approach to climate resilience, prioritising bushfire preparedness and mitigation, alongside strategies to manage increasing flood and heat risks. Community engagement and robust local planning are essential to navigate these challenges effectively.

The primary climate risk for Narracan is bushfire, due to its location adjacent to significant bushland areas and projected increases in hot, dry weather conditions.
How will climate change affect flooding in Narracan?
Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe localised flooding from Narracan Creek and stormwater runoff.
Are there specific bushfire overlays affecting Narracan properties?
Yes, Narracan is designated as a Bushfire Prone Area, meaning properties within the suburb are subject to specific building regulations and planning requirements related to bushfire risk.
What can I do to prepare my property for bushfires in Narracan?
Key preparation steps include maintaining a defendable space around your home, clearing gutters and downpipes, having appropriate fire-fighting equipment, and developing a household bushfire survival plan.
