This is the lowest energy of the tide-modified beaches and also has the coarsest sand.
Reflective + low tide terrace beaches have a steep cusped high-tide beach composed of medium to coarse sand, which changes at an abrupt break in slope into a low-gradient wide (av.120 m but can range 20-1000 m) low tide terrace composed of finer sand.
Typical breakers are 0.5-1 m high. At high tide waves surge at base of the steep beach face and there is no surf zone. At low tide there is a flat sand bar exposed, waves of > 0.5 m height plunge on the outer end of bar, and waves >1 m height may cut rip channels across the terrace. At high tide the deep water close inshore and steep beach face may cause a problem for the elderly and young children. At low tide stay on the bar inside breakers, if rip channels are present be aware of the seaward moving rip currents, also plunging waves can dump heavily on bar at low tide.
