The reef is expected to create waves of up to 13ft (4m)
Construction work on an artificial surf reef being built off Dorset will begin its final phase on Monday.
The reef off Boscombe, Bournemouth will create waves of up to 13ft (4m) when completed in September in a project which cost £2.7m.
It is part of an £8m regeneration scheme of the area which planners hope will boost the economy by £3m a year and attract up to 10,000 surfers.
Work was delayed on the project from November to April due to bad weather.
Temporary anchors and buoys will also be removed as New Zealand-based developer ASR fine tunes the project.
Shaw Mead, technical director, said: "Like any major construction project, there are extensive checks to be undertaken before we can say the project is complete.
"We are now starting to make all those checks thoroughly and according to the agreed specification, and I remain confident that we will finish in September as scheduled."
The land-based construction site has also started to close, allowing the public to use the beach.
The reef has been built with 55 sand-filled "geotextile bags", which will cover an area the size of a football pitch underwater.
It will be one of four artificial reefs of its type worldwide, including Narrowneck, Queensland, Cables, Western Australia and Mount Maunganui, New Zealand.
