Flood Risk in Penola, SA: 2026 Assessment

Penola, located in South Australia, has a notable flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across South Australia.

Local drainage infrastructure may be inadequate to handle increased rainfall intensity.

Penola faces a moderate risk of flooding, primarily from heavy rainfall events and local watercourses. The risk is expected to increase with climate change due to more intense rainfall.

For a comprehensive property-specific flood assessment including address-level elevation data, flood overlay mapping, and insurance cost estimates, use the ClimateNest full analysis tool. General suburb data cannot replace a site-specific evaluation.

Penola sits within ClimateNest's suburb-level hazard model for flood risk. 2.3% of the suburb's land area is mapped in high-risk flood zones and 81.2% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Penola.

Penola (postcode 5277) 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 (19.7% of land in high-risk zones), surface flood (8.7% of land in high-risk zones), riverine flood (2.3% of land in high-risk zones). Exposure is not uniform across Penola — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
