Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. Most places in the ocean usually experience two high tides and two low tides each day (semidiurnal tide), but some locations experience only one high and one low tide each day (diurnal tide).

Tide Timetables are essential for all who use the sea as a means for work and/or pleasure and can also be very useful to anyone who visits the coastline especially around the South Wales coastline.

The Tide Timetable for Porthcawl is listed in this section.
