Flood Risk in Valentine, NSW: 2026 Assessment

Valentine, located in New South Wales, 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 New South Wales.

Historical flood data indicates that properties close to the lake and creek are at higher risk.

Valentine is located near Lake Macquarie and Cockle Creek, making it susceptible to flooding from heavy rainfall and rising water levels. Climate change is expected to increase the intensity of rainfall events, potentially worsening flood risks.

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.

Valentine sits within ClimateNest's suburb-level hazard model for flood risk. 4.4% of the suburb's land area is mapped in high-risk flood zones and 69.1% 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 Valentine.

Valentine (postcode 2280) 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 (12.2% of land in high-risk zones), surface flood (5.3% of land in high-risk zones), riverine flood (4.4% of land in high-risk zones). Exposure is not uniform across Valentine — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
