In the framework of linearized wave theory, using the classical wave breaking criterion and longshore current formula, the following two extreme conditions are analytically derived; 1) the maximum angle between the breakerline and the shoreline occurs when the angle between wave fronts in deep water and the shoreline is about 66°; and 2) maximum longshore current velocities are obtained when the previously mentioned (deep water) angle is about 58°.
