The prevailing wind (the direction it usually blows from) causes waves to approach the coast at an angle. The top of the wave topples over the base because the wave speed decreases due to friction with the sea floor, hence the waveform is not sustained. Remember that in deep water, a waves speed depends on its wavelength, but in shallow water wave speed depends on the depth (section 10.1). The waves ultimately hit the beach at an angle (oblique to the beach) and this leads to the formation of the longshore current.
