![]() ![]() If you're boating, always wear a lifejacket or a buoyancy aid.If you’re in trouble in the water, and you have a board, always stay with it.In storm conditions exercise extreme caution near the coast and avoid exposed areas.Our advice is to stay clear of the edge, especially in large wave conditions, when the water level can raise by several metres with each set. But a particularly large ‘set’ is often responsible for washing anglers from rocks and coastal walkers into the sea. Closer to shore, waves typically arrive in ‘sets’ (a group of a few large waves one after the other) every few minutes, with a few minutes of smaller waves in between. This sudden increase in size can be hazardous for water users out at sea. The swell comes out of deep water and hits a very shallow short reef, so the swell breaks suddenly, producing an incredibly critical and powerful wave.’Ī ‘rogue’ wave occurs when waves that are travelling in different directions come together and combine their heights into one wave. I haven’t been to Hawaii, but there’s a spot called the Pipeline, which has the most perfect barrelling wave in the world. ![]() Australia, Costa Rica and South Africa have renowned surf spots, as do Portugal, France and Spain. Indonesia is a consistently good surf spot - you’ll get waves every day. ‘I’m still looking for the perfect wave, but there are great waves all over the planet. Jonathan Waugh, an RNLI Lifeguard on Porthmear Beach in St Ives, Cornwall, has been a surfer for over 20 years. ‘But how those waves interact with the coastline, such as bending round headlands, makes conditions on specific beaches harder to forecast.’ The perfect wave ‘On an open ocean scale, the science of predicting the size and timing of waves is very good,’ says Paul. Now, there are forecasting apps just a click away. In the past, forecasting waves was down to deciphering weather charts, tide conditions, wind conditions and having good local knowledge. And if you’re a windsurfer or kitesurfer, you need wind and waves, or wind-driven waves. You can see this effect at the popular surfing beaches of Croyde in North Devon and Fistral in North Cornwall. On UK beaches, that often occurs at low tide because beyond the low water mark beaches tend to drop off and there’ll be a steeper slope.’ ‘To get a good plunging wave, you need a steeper slope for the wave to break on, and an offshore wind to hold the wave up and delay it breaking. ‘The plunging breaker curls over at the top and forms a tube that surfers can ride in,’ Paul explains. The converse is the plunging breaker, which breaks in a more violent way, when the transition from deep water to shallow is greater. These waves are popular with learner surfers.’ ‘Spilling breakers topple over gently and spill shorewards, often accompanied by an onshore directed wind. ‘A spilling breaker is a gentle breaking wave and occurs on flat, gently sloping beaches, such as Polzeath in Cornwall,’ says Paul, who’s also a former European surfing champion. There are two types of breaker: a spilling breaker and a plunging breaker. The wave reaches a point where the crest is travelling faster than the trough, so the wave becomes unstable and breaks. When waves come into shallow water, they break.
