At a point break, the wave breaks around a point. This works if the swell does not hit the land directly but comes from the side. The special thing about such point breaks is that the wave can run very long, which means you can surf much longer on the same wave, as for example on a beach break.
Pointbreaks can break on sand or stone. The important thing is the swell hits from the side of a promontory - the point.
Well-known point breaks are for example: Los Lobos on Fuerteventura (breaks on a reef), Jandia / Cruz Roja on Fuerteventura (breaks on sand), Jeffreys Bay in South Africa (the wave breaks partly on sand, partly on rocks), Snapper Rocks in Australia (the wave breaks on sand), anchor point in Morocco (the wave breaks on stone) and much more.
