Tides have a deep impact in surfing. The rise and fall of sea levels affect the quality and the way waves break on the shores.
Tides are the result of the combined effects of the gravitational forces exerted by the Moon and the Sun with the rotation of the Earth.

There are three tide timings in the world.
When spots get two uneven tides a day - one high and low tides - that is called mixed tide. Coastal regions with a diurnal tide experience only one high and one low tide each day.
Tidal period is the length of time between successive high or low tides. These tidal periods change from spot to spot, but tides usually have a fundamental period of 24 hours 50 minutes (lunar day), or 12 hours and 25 minutes.
Tides influence current flow and, therefore, waves and their power to generate surf. Extreme high tides may produce waves that break on shore, while extreme low tides may drain water from the line-up resulting in dangerous close-outs.
When Sun, Moon and Earth are aligned, we get spring tides, with high waters higher than average and low waters lower than average. This happens roughly twice a month, in New Moon and Full Moon.
Neap tides work the opposite way. When the Moon is at first or third quarters, tides will be less extreme, which means there is no big difference between high and low tides.
