GLOSSARY
78 terms every surf school and board rental operator should know.
Waves generated by distant wind that have travelled across open ocean. Cleaner and more organised than local wind waves; the main driver of good surf.
Long-period swell from a distant storm. Produces powerful, well-spaced, orderly waves — usually the best surf.
Short-period swell from nearby wind. Waves are closer together, weaker and less clean than groundswell.
The cyclical rise and fall of the sea. Whether a break works depends heavily on tide state, which shifts through the day.
When the water is at its highest. Many beach breaks go soft or fat at high tide; some reef and point breaks only work then.
When the water is at its lowest. Can expose rocks and sandbanks and make some breaks dump or close out.
The window between low and high while the tide is coming in. Often the sweet spot for beginner beach breaks.
Wind blowing from land out to sea. Holds waves up and grooms them clean — the ideal wind for surfing.
Wind blowing from sea to land. Makes waves messy, bumpy and crumbly; too much onshore blows a spot out.
Groups of larger waves that arrive together, separated by calmer water. Surfers wait for and position for sets.
A quiet gap between sets when few or no rideable waves come through. A chance to paddle out or reposition.
Smooth, mirror-like water with no wind texture. Usually dawn or dusk in light winds — prized conditions.
Small, disorganised surface bumps caused by wind. Makes riding and paddling harder.
When strong onshore wind has ruined the surf, leaving it messy and unrideable. A common reason to reschedule lessons.
The time in seconds between swell waves. Longer periods (12s+) mean more powerful, cleaner surf; short periods (under 8s) mean weak, choppy waves.
Waves that break over a sand bottom. The safest, most forgiving break type — where nearly all surf lessons happen.
Waves that peel along a headland or point, often giving long, predictable rides. Usually better for improvers than beginners.
Waves that break over rock or coral. Can be powerful and high-quality but hazardous — rarely used for beginner lessons.
A peak that breaks in both directions, offering a left and a right from the same spot.
A wave that breaks all at once along its length rather than peeling, giving no rideable shoulder.
The hollow part of a breaking wave a surfer can ride inside. The most sought-after and advanced manoeuvre.
The foamy broken part of a wave after it has crashed. Where beginners catch their first waves.
The unbroken, open face of a wave ahead of the whitewater. Catching green waves (rather than whitewater) is a key beginner milestone.
The area beyond the breaking waves where surfers sit and wait to catch waves.
The highest part of a wave where it first begins to break — the takeoff point.
The unbroken part of the wave face to the side of the peak, where the ride continues.
A wave that peels to the surfer’s left as they ride it (appearing to break right when viewed from the beach).
A wave that peels to the surfer’s right as they ride it (appearing to break left from the beach).
Waves that break directly on the sand at the water’s edge. Can be punchy and is a common cause of board dings.
A board with a soft foam deck. Stable, buoyant and safe — the standard beginner and lesson board.
A board 9ft or longer with lots of volume. Easy to paddle and catch waves on; good for beginners and cruising.
A mid-length board (roughly 7–8ft) balancing stability and manoeuvrability. A common progression board for improvers.
A short, low-volume, high-performance board (typically under 6’6). Hard to paddle and catch waves on; for experienced surfers.
A shorter, wider, flatter board with a swallow tail. Fast and fun in small, weak waves.
The buoyancy of a board measured in litres — the key metric for matching a board to a surfer’s weight and ability, more important than length.
The curve of a board from nose to tail. More rocker suits steep waves; less rocker paddles and glides better in small surf.
The edges of a surfboard. Fuller rails add stability; thinner rails allow sharper turns.
Foils on the underside of the tail that provide grip and control. Removable or glassed-in.
A three-fin setup — the most common configuration, balancing drive and manoeuvrability.
A one-fin setup, common on longboards. Smooth and stable, less loose than multi-fin boards.
Two common board core materials — EPS (expanded polystyrene) is lighter, PU (polyurethane) is a heavier traditional foam. Affects durability in rental use.
The core beginner skill: springing from lying to standing in one motion as the wave picks up the board.
The moment of catching a wave and getting to your feet at the peak. The hardest part to time.
Getting from the beach out to the lineup, paddling over or through the incoming waves.
Pushing a shortboard underwater to pass beneath a breaking wave while paddling out. Not possible on high-volume boards.
Flipping a longboard or soft-top upside down to let a broken wave pass over it. The beginner alternative to a duck dive.
The first turn at the base of the wave after take-off, setting up the rest of the ride.
Falling off the board while riding or taking off. A normal, expected part of learning.
The number of students per instructor in a lesson. Lower ratios (e.g. 4:1 or better) are standard for beginner safety and progression.
An entry-level surf coaching qualification (e.g. from the International Surfing Association) certifying someone to teach beginners.
A first lesson in the broken foam close to shore, where students learn the pop-up before progressing to green waves.
A neoprene suit that keeps a surfer warm in cold water by trapping a thin layer of water against the skin.
A common wetsuit thickness — 3mm on the body, 2mm on the arms and legs. Suited to mild-to-cool water.
A thicker winter wetsuit — 5mm body, 4mm limbs — for cold water, usually worn with booties, gloves and a hood.
Neoprene boots that keep feet warm and protect against rocks and reef.
The cord connecting a surfer’s ankle to the board so it doesn’t wash away after a wipeout. A basic safety item, checked before every rental.
Grippy wax rubbed onto the deck so the surfer’s feet don’t slip. Needs topping up regularly on rental boards.
A grippy foam pad stuck to the tail deck as an alternative or supplement to wax, mainly on shortboards.
A thin top worn against the skin or under a wetsuit to prevent rash from the board and wax, and for sun protection.
Damage to a board’s outer skin — a crack, gouge or hole — that lets water into the foam if left unrepaired.
A strong, narrow channel of water flowing out to sea. The main ocean hazard for surfers and swimmers; instructors teach how to spot and escape one.
The rule of who gets the wave — generally the surfer closest to the peak (the curl) has priority.
Taking off on a wave in front of someone who already has right of way. The most serious breach of surf etiquette.
Paddling around another surfer to steal priority for a wave. Considered poor etiquette.
The designated area where surfing is permitted, often kept separate from swimming zones by flags.
Beach markers set by lifeguards to separate swimming and surfing areas and indicate conditions. Lessons run within permitted zones.
A surfer’s capacity to swim unaided — declared on the waiver before a lesson, as it directly affects water safety.
The body’s involuntary gasp reflex on sudden immersion in cold water. Wetsuits and a proper entry reduce the risk.
A lesson with several students and one instructor at a set ratio, priced per head. The core surf school product.
One-on-one (or two-to-one) coaching at a higher rate for faster progression.
Hiring a board (and often a wetsuit) without a lesson, typically by the hour, half-day or day.
The signed liability agreement, including a swim-ability declaration, completed before a surfer enters the water.
Building lesson slots around the tide window rather than fixed clock times, so sessions land when the surf actually works.
A pre-authorisation on the surfer’s card at booking covering potential board damage. Released automatically on a clean return.
A single booking covering several surfers — a family, stag or corporate group — under one booker, invoice and deposit hold.
Sealing a damaged board so water can’t reach the foam. Minor dings are a quick UV-resin fix; deeper cracks need traditional resin work.
A booked surfer who doesn’t turn up. Recovered day-of with a rebook link while they’re still near the beach.
The busiest stretch of the surf calendar — usually summer — when lessons, rentals and staffing all run at capacity.
