The Southern California coastline remained under a high-surf advisory on Tuesday after a huge swell crashed up along SoCal beaches Monday.

The National Weather Service cautioned beach goers and swimmers to be extremely careful before heading into the water. At the Manhattan Beach pier, people watched as waves crashed underneath the pier.

Roger Nicholas of New Jersey is one of the many people who came to see the 10 to 12-foot waves.

“Absolutely amazing. I’ve never seen waves like this,” Nicholas said.

Nicholas spent the day capturing photos of the waves as each crashed against the pier. As Nicholas took in the sights, surfers mostly stayed on the sand.

Francis Hillebrand usually surfs off Manhattan Beach. Aside from a road trip to the mountains, he said the waves are out of his comfort zone.

“I can’t handle these waves, simply. It’s hard enough for me to paddle out given these conditions and Manhattan Beach doesn’t have a lot of channels,” Hillebrand said.

Most people played it safe at the beach, keeping close to the shore.

Erin Bourland, a Manhattan Beach resident, came to the pier with her mom before heading to the airport. She said seeing the waves would be exciting for daring surfers.

“They look really fun but they definitely look dangerous so you have to know what you are doing before you go out in the water. For sure,” Bourland said.

Just like Bourland, the crashing waves inspired Nicholas to one day take on the challenge.

“These are a little bit too much for a first timer. But, it is encouraging. Because I would like to ride waves like this one day,” Nicholas said.

But, for now, Nicholas will hold onto his photos as an inspiration to come back one day and surf these waves when he’s ready.

The National Weather Service is asking swimmers to take caution when entering the water by following these tips: - If you are caught in a rip current, don’t swim against the current - Swim in an area near a lifeguard - Never leave children unattended.

The high-surf advisory is expected to remain in effect until 10 p.m. Tuesday night.
