The longshore current in the inshore region flows which direction relative to the shoreline?

Waves hitting the shore at an angle push water up the beach obliquely and, as it runs back seaward, creates a steady flow that stays along the coast. This alongshore flow in the inshore (surf) zone is the longshore current. It moves parallel to the shoreline, driving sediment transport along the coast (littoral drift). Directions toward or away from the shore aren’t the typical motion of this current in the inshore region, though cross‑shore flows can occur in rip channels separate from the longshore current. Therefore, the current in the inshore region is parallel to the shoreline.
