The Flooding Character of Ocean County

Coastal flooding is the dominant flood character in Ocean County, NJ, with 140 recorded events in the last 30 years. Recent events include coastal flooding observed in October 2025, where a coastal storm caused strong winds to push water towards the shoreline and into back bays, leading to moderate to locally major high tide levels. Another coastal flood event in October 2025 resulted from an area of low pressure causing onshore easterly flow, pushing water towards the coast and back bay communities, leading to moderate tidal flooding.

The National Flood Insurance Program (NFIP) data shows a significant number of claims in Zone A, with 40,629 claims averaging $46,204. Properties in Zone A and Zone V, which have experienced the most claims and highest average payouts, should pay particular attention to flood risk. Homeowners in coastal areas and those located near back bays are most likely to be affected by these events.
