Swell is the term used among surfers to designate a set of waves that separate and move away from a storm or weather phenomenon that develops in the ocean. The waves used for surfing, are those formed from the moment the mass of water hits the specific point where the sea or ocean begins to be less deep.
- The amount of time it takes for two successive wave crests to pass through a determined point is called swell period or wave interval. The swell period is critical surf knowledge because it ultimately measures the quality of the upcoming surf session.

What is a good swell for surfing?
Swell size The size of the wave, or swell height, is a measure in feet or meters. If the surf forecast says 1-3m (3-9ft), then it’s usually a good time to go surfing. 3m waves are not appropriate for beginners, but experienced surfers take on waves of incredible height.
What is a swell in surf terms?
Swell is energy that has been transferred into the sea by wind. The longer and stronger the wind blows (like a hurricane) the more energy that is transferred and so larger the swell. This energy then propagates from where it is created out into the ocean, much like ripples in a pond.
What causes a surf swell?
Large surf is caused by swells, which are created by large storms blowing over the ocean surface. The size of the swell depends on the intensity of the wind within a storm, the amount of distance the wind blows across the water (called the fetch), and the amount of time the wind blows at a sustained speed.
Do swells cause big waves?
Swell Period, Height and Direction Long-period swells harness energy, travel faster, and easily cope with local winds and currents, resulting in larger beach waves. The first waves of a long-period swell are called forerunners and usually move faster than the remaining carriages of the wave train.
Is swell good for surfing?
In general groundswell produces waves that are much better for surfing. Wind swell is usually smaller, and almost always choppier and harder to surf than groundswell. Although both are present at most surf spots, groundswell creates much better breaking waves and dominates the lineup.
Can you surf a swell?
Both types can create great waves to surf, but, ground swell is usually best. The swell size and direction need to be looked at together with geography of the coastline you are surfing. If a surf spot faces directly into, say a 3m swell, you can probably expect waves around the 3m mark.
What is a surfer girl called?
There is no specific term for a female surfer. You can call a girl who surfs just “surfer”, although, there are terms like gurfer, wahine that are used to refer to a female surfer.
What is swell period?
In simplest terms, swell period refers to the timing of a set waves that are coming in. According to Surfline, “By definition, swell period/interval is the time required for one complete wavelength to pass a fixed point, and it is given in seconds.”
What are the different types of swell?
There are three different types of swell that you should understand: Ground Swell, Wind Swell and Hurricane Swell.
What’s the difference between a wave and a swell?
Waves are generated by wind moving over water; they indicate the speed of the wind in that area. Swell are waves (usually with smooth tops) that have moved beyond the area where they were generated.
Why is it called a ground swell?
The groundswell owes its name to the fact the energy of long period waves extends down and comes into contact with the ocean floor earlier, at a depth of around 1,000 feet, while wind swells only touch the bottom of the sea at about 50 feet.
What is a ground swell?
1 usually ground swell: a broad deep undulation of the ocean caused by an often distant gale or seismic disturbance. 2: a rapid spontaneous growth (as of political opinion) a groundswell of support.
What is the difference between ground swell and wind swell?
A groundswell and a wind swell are both created by the wind blowing above the ocean. In a scientific standpoint, these are the same. A big difference between ground swells and wind swells is that waves from a ground swell can travel a big distances without losing any energy and wind swell don’t.
How high can ocean swells get?
With a height of up to 29.1 meters (95 feet) from trough to crest, the single waves are the highest ever measured. In terms of so-called significant wave height, they established a new record, according to the scientists: 18.5 meters (61 feet). Significant wave height is the median height of a wave’s upper third.
How fast does swell travel?
The speed of travel of the deep water swell group will be 1.5 times the swell period; ie: a 20 second swell will be traveling at 30 Nautical mph. The actual individual waves will be traveling at three times the swell period, so a 20 second swell will have waves moving at up to 60 Nautical mph.
