When there is a local area which is slightly deeper, or a break in an offshore sand bar or reef, this can allow water to flow offshore more easily, and this will initiate a rip current through that gap.

Bearing in mind the above, the worst thing you can do when stuck in a rip current is panic and/or try to swim or paddle directly against it; this almost invariably fails, and leads instead to fatigue, which is when rip currents become dangerous and lead to drownings. PkBn � b�o+�Z�ӿ���@ ���G���� Rip currents can be killers — but they’re generally speaking harmless to those who know what they’re up against.

Rip currents likewise flow only in an offshore direction. Rip currents are found along most coastlines, and where they form near popular beaches they can be deadly. The best way to imagine a Rip, without seeing a beach is by looking at a diagram (see below); Imagine this is a beach from above.

A rip current is a narrow, powerful current of water running perpendicular to the beach, out into the ocean. 10 0 obj

When water is pushed towards the shore by waves — which break over sandbars, where the water is shallower — it flows back out to sea following the path of least resistance.

You will soon find yourself out of the rip and in a position to return safely to shore.

What changes is your joy and appreciation of it…". 11 0 obj Rather than paddling out through the breaking waves and being repeatedly pushed back towards shore, experienced surfers may actively seek out rip currents as a more efficient route for getting out into the line-up.

A rip current is a body of water moving back out to sea, and often dragging unsuspecting swimmers and surfers with it. Bear in mind that around piers and groynes, the current is often significantly stronger, and often impossible to escape from (see below). The Police have issued a statement urging for an end to the "dangerous" behaviour. The BBC is not responsible for the content of external sites. The above refers primarily to beach breaks, where waves break over a sand bottom and rip currents are most prevalent, but the basic principle applies to reef breaks too. If you’re able to touch the bottom then wade your way to safety, otherwise paddle at a perpendicular angle to the flow of the rip current (parallel to shore). In fact, such currents are more accurately described as longshore drift or longshore current (the defining characteristic of a rip current is that it goes out to sea). A rip current forms because wind and breaking waves push surface water towards the land, and this causes a slight rise in the water level along the shore.

Generally speaking, the larger and more powerful the surf, the stronger the longshore current is likely to be, although this isn’t the only factor involved, and the longshore current can be negligible on even the biggest of days. k1C�v���8�i� �f�EY �;^tW`�ܠʵ���Sk��G�51��dH�Y�5$qޏ7��׍�j$o1��@OD̋�H�}��,�S_��6C7dH�3Q@ ��n;���!׎~�Q�ʢqW��k]V�Ͻ���"!B�������oH�
