Why does Sea water come close to shore at night?

Waves are mostly caused by Friction of wind on surface of water. Wind blows from sea to land in day and land to sea in night due to pressure and temperature difference. So it is intuitive why there are waves towards shore in day, but even in night there are waves towards shore.
