(KHNL) - The big surf began to roll in and so did the crowds.
Traffic moved slowly as people rushed to the beaches to watch the monster waves pound the north shore.
Stephanie Kennedy is visiting family in Hawaii. She's from Minnesota.
"It's amazing. We were even scared to let the kids get too close. It looks like they could get pulled right out," said Kennedy.
Pat Kelly with Ocean Safety said, "This is the biggest swell we've had yet this season."
And for this reason, life guards made sure to keep people out of the water and behind warning signs.
Verlene Breckenridge has never seen anything like this coming from Kansas.
She said, "I think it's the most awesome thing I've ever seen. These waves are tremendous."
But lifeguards warn these waves are beautiful, but dangerous.
Kelly said, "People want to get really close to waves and they can get swept off rocks or they could get swept off the beach. These conditions can be very dangerous."
Ocean safety officials say the waves were blown out and choppy, not ideal for the most experienced surfers.
But for Justin Garo of Mililani, they're perfect for viewing at a distance.
