TEAHupo'o
Teahupo'o (pronounced "Cho-Po") is located off the southwest coast of Tahiti and is famous for its heavy (super thick) waves. What's particularly interesting and notable about this spot is that people have only surfed it for about 15 years, because before then it was believed that the wave was too dangerous and steep to surf. Then around 2000, famous Laird Hamilton ventured out and surfed there and proved that the waves were in fact surfable. Although Teahupo'o does get to be a bit big (about 30 feet sometimes), the truly astounding thing about this wave that sets it apart from all other surf spots is how immensely thick the wave is. The shape of the wave is caused by the bottom features here, and how the bottom rises up so quickly and so steeply, and because of this it is a surging wave (because the wavelngth and wave sizes compared to the steepness ratio make it impossible for the wave to break "normally" and instead it "surges"). This rapidly rising bottom makes the waves very fast, barrel well, and super steep. Like with Hawaii, bottom features like reefs were formed by past volcanic activities. Usually these reefs would make the waves big, but sloppy, which is the opposite of the very well-formed and clean waves of Teahupo'o. So what's unique about the reefs of Teahupo'o is that there are multiple channels between reefs that allow water from the shore to quickly and easily release back into the deep ocean, which is why the waves here are so clean. These channels are caused because they are where freshwater from rain and other sources would rush back into the ocean, and coral needs a certain salinity to grow, so it did not grow in these freshwater channels. In these channels with no reefs, waves do not break, so boats and jet-skis often sit in these safe areas. Also, these channels of water going back to the deep ocean make it so the waves do not ripple like normal, and consequently make them super thick when they rise up of the water because "water being funneled out builds up the thickness of the wave"(Science of Teahupo'o).
Yet another unique characteristic of this surf break is that the waves do not really have any height in the back and it looks more like the front of the wave just dropped into the ocean. This is also due to the steep reef that makes the bottom of the half of the wave stop and push back up against the flow to fill in through the back of the wave.
