Q. What happens to waves in deep water?
When deep-water waves move into shallow water, they change into breaking waves. When the energy of the waves touches the ocean floor, the water particles drag along the bottom and flatten their orbit (Fig. When this happens, the front surface of the wave gradually becomes steeper than the back surface.
Q. What happens when waves reach the shore?
As waves come into shore, they usually reach the shore at some angle. As a wave comes into shore, the water ‘feels’ the bottom which slows down the wave. So the shallower parts of the wave slow down more than the parts that are further from the shore. This makes the wave ‘bend’, which is called refraction.

Q. How do waves shape the shoreline?
Waves carry sand up the shore parallel to their direction of travel. The waves wash back into the ocean perpendicular to the shoreline. This causes sand to move in a zig-zag pattern parallel to the shoreline.
Q. How high is double overhead?
wave heights for surfing
| wave height in feet | distance from base to lip of wave measured on front of wave |
|---|---|
| 8 – 10 ft. | 3 feet overhead to double overhead |
| 8 – 12 ft. | 3 feet overhead to double overhead+ |
| 10 – 15 ft. | 2 to 3 times overhead |
| 12 – 15 ft. | triple overhead |
Q. What is double overhead?
Double overhead. A wave twice as tall as its rider. Double-Up. A type of wave that is really more like two because the more obvious, larger wave, has another wave developing from its wave face.
Q. Are 3ft waves big?
As far as I’m concerned, three feet is the perfect size for a wave. It’s big enough that you can ride a shortboard and still have some decent faces to work with, but it’s small enough to bust out the longboard and work on your nose-riding without worrying about bouncing your head off the reef.
