How do you describe swell direction?

What is a good swell for surfing?
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 rating?
The Swell Rating is determined by concatenating the Swell Category and Swell Quality components. The resulting number defines the value, or signature for the swell and resultant breaking waves at the time the observations are taken.
How do you read a swell interval?
Wave Period and Wave Conditions
- 1-5 seconds: Local wind swells with bumpy and disordered waves. …
- 6-8 seconds: Regional and local wind swells with average surfing conditions. …
- 8-10 seconds: Medium-distance swells improve the local surfing conditions.
What size wave is good for beginners?
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).

wave heights for surfing
|wave height in feet||distance from base to lip of wave measured on front of wave|
|3 – 4 ft.||waist to shoulder high|
|3 – 5 ft.||waist to head high|
|4 – 5 ft.||shoulder to head high|
|4 – 6 ft.||shoulder high to 1 foot overhead|
How do you predict surf swell?
Swell period is an important factor in surf forecasting. It is a measurement of time between successive waves in seconds. If you multiply the swell period by 1.5 you will calculate the speed in knots of the wave group for deep water. Waves travel in groups, with the individual wave traveling twice as fast the group.
Tiny surf is really unforgiving when it comes to turning. A one- or two-foot wave is usually good for one, maybe two turns. Pick your section wisely, as you may only get one chance to turn–don’t blow that chance. “On a tiny wave, a big move is likely to be your last,” says Taj Burrow.

What is primary swell and secondary 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.
What is swell energy kJ?
Wave energy (in kilo Joules, kJ) on the swell forecast tables and maps indicates the power of the predicted waves and can be the most useful guide to how powerful the surf is likely to be at your local beach / reef. … This should give you the energy range that is in your comfort zone.
What is a good wave period for boating?
For boaters, long wave periods (e.g., 12 seconds) are better for sailing because it typically means most of the waves will be swells which means a smoother ride for small boats.

Why do polymers swell?
When a solvent is added to a crosslinked polymer, the polymer will swell. The amount of swelling depends on two factors: … The length (or, in this theory, the MWt) of the chains between crosslinks. Obviously the shorter the length (the higher the crosslink density), the less the swelling.
How do you calculate sea wave height?
The wave height is the vertical difference between a wave crest and a wave trough. The wave length is the horizontal distance between two consecutive wave crests. The wave period is the time interval between two consecutive wave crests. The wave velocity (celerity) equals the wave length divided by the wave period.
What size wave is considered big?
They will likely agree with the common understanding that for surfing to be considered ‘big wave’ surfing, the waves must be at least 20 feet high. Surfers that are charging waves beyond 20-feet are legitimate big wave surfers.

How big is a 2ft wave?
The Traditional scale corresponds to approximately one half the height of the wave face, i.e. a wave estimated to be 4 feet from crest to trough (or chest-shoulder high on the average surfer) would be called 2 feet.
Most surfers will call an average height rather than basing a session on rogue set waves/ the biggest of the day. … As a general rule, if it’s only 1ft, it’s pretty difficult to surf on, unless you longboard or are a lightweight grom/ shredding machine!
