High tide happens on the side facing away from the Moon too.

The Moon pulls the near-side water more strongly than Earth's centre, and the centre more strongly than the far-side water. The result is two bulges: one toward the Moon, one opposite. Earth rotates beneath both, so most coasts get two high tides a day. The Sun contributes about 46 % of the Moon's effect.

Useful: At new and full moon, Sun and Moon add up to spring tides; at half moon they partly cancel into neap tides.
