Bad weather delayed the construction of the artificial surf reef
Europe's first artificial surf reef incurred an additional cost of more than £250,000, it has emerged.
Bournemouth Borough Council part-carried out harvesting and filtering work of sand which fills the bags that enable it to work, due to bad weather.
It is now looking to recover some of the cost from contractors ASR Ltd, an audit committee report has revealed.
The council said the overspend was included in the £3m cost of the project, which had doubled in price.
An audit committee will meet on Wednesday to discuss the reef.
The surf reef - which improves the surf by enhancing the waves off the Boscombe coast - officially opened on Monday, more than a year late.
It was created to improve surfing conditions using 55 sand-filled "geotextile bags" which are 225m (740ft) out to sea.
It is part of an £11m overall regeneration of the seafront.
Tourism chiefs have enlisted the help of a specialist team at Plymouth University to monitor the reef's performance over the next 12 months to assess whether it is delivering the surfing conditions expected.
