As swells arrives at the beach, shallow water forces waves to slow down and rise up above the surface, morphing as it goes through a process known as “wave shoaling”. Surf is swell that has arrived in shallow enough water to rise up above the surface, and break.

Is swell the same as wave height?
Swell height refers to the average size of the swell out at sea. This is measured from the peak to the trough and the seconds between one peak and the next using historical and real time data gathered from offshore buoys. Wave height is the average wave size a surfer may expect to see when reaching the beach.
Is a 2m swell big?

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.
Are oceans and seas the same thing?
Many people use the terms “ocean” and “sea” interchangeably when speaking about the ocean, but there is a difference between the two terms when speaking of geography (the study of the Earth’s surface). Seas are smaller than oceans and are usually located where the land and ocean meet.
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.”

Does Tide affect swell?
On incoming tides, the deeper water enables the raw swell energy to move a little closer to shore with less of a friction factor from the bottom.
What is a good wave height for beginner surfers?
GOOD WAVE HEIGHT FOR BEGINNER SURFERS? Generally speaking the smaller the better — but not too small that you can’t get moving. This usually means waves in the 1.5 – 2ft range (occasionally 3ft if you’re up to it).

How big do 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 big should a boat be for the ocean?
You can fish offshore in a boat as small as 10 feet, although it’s best to have a boat at least 15 feet long for safety and efficiency when fishing offshore. Boats up to 30 or 40 feet may be appropriate for some kinds of offshore fishing.
What is HS wave height?
Significant wave height (Hs) is defined as the average height of the highest one-third waves in a wave spectrum. This happens to correlate very well with the wave height a skilled observer perceives in a wave spectrum.
What is first and second swell?
When the primary swell is between 6 and 8 metres, second swell is included if it is greater than 2 metres and from a different direction. When the primary swell is between 8 and 10 metres, second swell is included if it is greater than 2.5 metres and from a different direction.
