Wamberal Lagoon, an intermittently closed intermediate saline coastal lagoon, is located on the Central Coast region of New South Wales, Australia. Wamberal Lagoon is located between the beachside settlements of Forresters Beach and Wamberal, and adjacent to the Pacific Ocean, about 87 kilometres north of Sydney.
Fed by stormwater runoff that flows into Forresters Creek, the lagoon has a surface area of approximately 50 hectares and a catchment area of 5.8 square kilometres. When full, the Wamberal Lagoon covers an area of around 50 hectares. Its outflow is to the Tasman Sea of the South Pacific Ocean that is generally closed, and water levels inside the lagoon are not usually influenced by ocean tides.
The lagoon and the surrounding land comprising 139 hectares form part of the Wamberal Lagoon Nature Reserve, a nature reserve created in 1981, that is under management of the NSW National Parks & Wildlife Service.
Terrigal Lagoon and Avoca Lake are located to the south and are a short distance away.
