Giant waves in Hawaii aren't a new thing.
Pipeline is one of the most famous big waves in the world, and in the world of surfing. So staying in Hawaii you should probably know, big waves crash on the beaches there. And if one wave is huge, the ones that follow will also be massive. So standing close to them might result in injury, just saying.
Luckily, no one was injured. Personally, rocks and water only go well in drinks not it massive ocean waves crashing on beaches. I've ripped my body apart enough surfing on reefs to know I don't like rocks and waves.
