Claymore sits within ClimateNest's suburb-level hazard model for flood risk. 5.2% of the suburb's land area is mapped in high-risk flood zones and 76% 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 Claymore.
On ClimateNest's 0–10 suburb hazard index, Claymore scores 3 for flood risk — a lower exposure relative to the Australian suburb range. For comparison, properties in Claymore can still sit well above or below this suburb average depending on elevation, distance to waterways or vegetation, and local drainage.
Claymore located in Greater Sydney (postcode 2559), is a New South Wales suburb tracked by ClimateNest. The suburb's median property value is $1.6 million, and understanding climate exposure is becoming a standard part of due diligence for buyers, lenders and insurers pricing property in Claymore.
Across the six hazard axes ClimateNest models, the dominant climate risk in Claymore is extreme heat (score 5/10), with moderate exposure.

What share of Claymore is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 9.9% of Claymore in high-risk zones for surface flood, with a further 83.7% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
