It's the night before what could be one of the biggest swells on record. All through the North Shore are reminders about the danger of being this close to the ocean when big surf is set to roar ashore.
"Right now is the calm before the surf and [on Wednesday] we are expecting extremely dangerous surf so if anybody puts their lives in jeopardy they're also going to be putting our lifeguards lives at risk so we're just asking everybody to stay out of the water and stay far away from the shorelines," said Emergency Medical Services spokeswoman Shayne Enright.
Lifeguards put up caution tape across surf spots. Civil Defense closed Waimea Beach Park just before sunset on Tuesday.
But, the warnings won't stop big wave surfer Jamilah Starr who lives for these kinds of days.
"These are the kinds of things that we wait for and we pray for," said Starr.
The National Weather Service says this is a once-in-a-decade high surf event.
"These swells are pretty rare," said Starr. "Whatever happens we'll know [on Wednesday]. When it's over 20-plus, it's all big."
Some beachfront residents near Rocky Point are all too familiar with the dangers of a large westerly swell. Three weeks ago, their homes were hanging on a cliff, after a small swell hit in the same direction and wiped out parts of their property.
This time, they feel prepared after boarding up and building a temporary wall. Still, some plan to play it safe, and evacuate to higher ground.
"All the little kids, we're going to relocate [Tuesday night]. We have a good place and maybe the next day too," said Starr.
Even though Wednesday's waves are expected to be large enough for the Eddie Aikau big wave contest, it's still a no-go because weather conditions just aren't right.
The state Department of Land and Natural Resources has also closed Kaena Point State Park.
