Blowhole dangers: What you need to know

The internet is full of video of people doing reckless things at Nakalele Point in Hawaii and other blowholes.

"This kind of situation can be pretty treacherous," Howe said as he watched a clip of tourists getting knocked onto sharp rocks at Nakalele by a large set of waves.

"Really there's a whole number of hazards here. The hazard of being knocked down and pushed into the blowhole is one," Howe said. "Another hazard is being knocked down and swept back down into the ocean, something that we see quit frequently."

A different video shows someone standing over a blowhole with a camera as a torrent of water erupts from the hole knocking the cameraman off his feet. And another clip shows a man tempting fate by partially straddling a blowhole as water shoots skyward.

In 2002, Daniel Dick, a teen from California, drowned when he fell into Halona Blowhole near Sandy Beach on Oahu's East side.

It is safe, Howe said, for a person with knowledge of local conditions to approach a blowhole BUT only when ocean conditions are calm (no waves crashing onto the rocks and no spouts from the blowhole.) But lifeguards say if a blowhole is pumping ... STAY AWAY. They advise people to never turn their backs on the ocean. They urge people who are unfamiliar with conditions or terrain to ask someone with local knowledge about the dangers.

"The other thing is you can look for the obvious physical signs of the rocks themselves being wet," Howe said explaining that wet rocks at a specific location are a tell-tale sign water can reach that location. And if water can reach a location people standing there can be knocked off their feet and swept away.

People who fall into blowholes are almost always doomed - rescue is virtually impossible.

"If someone is dragged back into one of these blowholes, there's really not much anybody can do without placing their own life at risk. We would do everything we could to get you out, but without some kind of rope or something, and you can't talk (because of the noise created by the blowhole); if you look down into these things, they are full of wana (sea urchin). They are just razor sharp. It wouldn't do anyone any good to go in after somebody because they would parish as well," Howe concluded.
